The constructor of MemoryProxy initializes 3 of 4 instances variables.
If a MemoryProxy is constructed and MemoryProxy::free is called
on this instance, buffer_ is undefined and 'delete buffer_;' causes errors.
Although this misuse pattern does not exist in the current codebase
it already tripped up the Address Sanitizer on various occasions
while debugging unrelated problems.

The crash was caused by allocating an uninitialized amount of memory.
This fix initializes a bunch of variables that could cause the error.
It should be possible to also fix this in the function that actually uses
the uninitialized memory, but that could cause unknown consequences
that are a bit too risky for 3.0. Just initializing some variables should
be safe though. For more details see D13369.

This commit adds functionality for operations that require pixel
translation or resizing on "Full Frame" mode, allowing to adjust
their canvas. It fixes most cropping issues in translate, scale,
rotate and transform nodes by adjusting their canvas to the result,
instead of the input canvas.
Operations output buffer is still always on (0,0) position for
easier image algorithm implementation, even when the
canvas is not.
Current limitations (will be addressed on bcon2):
- Displayed translation in Viewer node is limited to 6000px.
- When scaling up the canvas size is limited to the
scene resolution size x 1.5 . From that point it crops.
If none of these limitations are hit, the Viewer node displays
the full input with any translation.

Some operations can take a lot of time to execute and
any duplication should be avoided.
This patch implements a compile step that detects
operations with the same type, inputs and parameters that
produce the same result and merge them. Now operations
can generate a hash that represents their output result. They only
need to implement `hash_output_params` and hash any parameter
that affects the output result.

When using a Cryptomatte node and selecting 2 views in Multi-View,
its output values are doubled. When selecting 3 tripled and so on.
This causes incorrect compositing results for all the views.
The node creates an input operation for each rendered cryptomatte
pass. In Multi-View, passes are rendered for each view but compositor
is executed per view and should only create operations for those
corresponding to the current view being executed. Otherwise duplicated
operations add up later in cryptomatte operation.

Adds full frame implementation to these nodes operations.
When enabling "extend bounds" node option, tiled implementation
result is slightly different because it's using `TranslateOperation`
with bilinear sampling for centering.
Full frame always uses nearest to don't lose image quality.
It has the disadvantage of causing image jiggling on backdrop
when switching size values as it's not pixel perfect.
This is fixed by rounding to even.

Current sampling methods have off by one issues on full frame:
- Bilinear sampling do not fully sample bottom and left image border,
creating edges.
- Single elem buffers are not sampled at all when they should be
at least on the borders to smooth edges.
- EWA filtering is partially implemented on `ReadBufferOperation`, it
needs to be moved to `MemoryBuffer` on full frame.
In order to not affect tiled implementation, this commit creates
specific sampling methods for full frame needs.

It was only affecting tiled fallback on full frame mode. If tiles from a
constant operation were multi-thread initialized, its buffer
was inflated multiple times.
Adds full frame implementation to "Bokeh Image" node, "Track Position"
node, `SetVectorOperation` and `MovieClipAttribute`.
The other nodes in "Input" submenu are implemented separately.
`MovieClipAttribute` needs resolution to calculate its constant value, it can't be constant folded,
which requires it to be a `ConstantOperation`. Now `ConstantOperation` contemplate this case
and any operation that is always constant without depending on inputs should implement it.
If in the future an operation needs to get an input constant element during
`determineResolution` it must first determine its input resolution.
The nodes have no functional changes.

It's the case of Image or Movie Clip node when not selecting any
source or an empty one.
Render methods expect an output buffer with size, only render
operations with resolution.
When fixing issues, seeing operation results can be helpful for
detecting which operation went wrong.
This commit adds an option for exporting all operations results to
image files.
Exceptions are:
- Output operations: They are already exported or can be seen in UI.
- Constant operations: There are too many and is rarely useful.
They are exported to "<temp session folder>/COM_operations/"
with filenames "<operation class name>_<operation id>.png".
Only works on full frame execution mode.

Currently we mostly iterate buffer areas using x/y loops or through
utility methods extending from base classes.
To simplify code in simple operations this commit adds wrappers for
specifying buffer areas and their iterators for raw buffers with any
element stride:
- BufferRange: Specifies a range of contiguous buffer elements from a
given element index.
- BufferRangeIterator: Iterates elements in a BufferRange.
- BufferArea: Specifies a rectangle area of elements in a 2D buffer.
- BufferAreaIterator: Iterates elements in a BufferArea.
- BuffersIterator: Simultaneously iterates an area of elements in an
output buffer and any number of input buffers.
- BuffersIteratorBuilder: Helper for building BuffersIterator adding
buffers one by one.
For iterating areas coordinates it adds `XRange` and `YRange` methods
that return `IndexRange`.

Link sockets are always connected to inserted translate or scale
operation `Color` sockets even when they have different data type.
This causes crashes on full frame mode when operations read inputs
with non expected datatypes.
Because data type conversions need to be executed before, convert
resolutions must ensure same datatypes are linked.
Work scheduler needed initialization and execution models are
not created during constant folding. This moves work execution
method to execution system.
