This patches removes common_math_utils includes from compositor shaders
and replaces them with math lib includes. This involves moving some
functions from that file to to the math lib files.

Previously, the vector type in the compositor had 4-components to
accommodated float4 types, while the last component was ignored for the
rest of the vector types. But now that we have a dedicated type for
float4 in #134486. We can reduce that vector type to 3-components.

The compositor previously overloaded the vector type to represent
multiple dimensions that are always stored in a 4D float vector. This
patch introduce a dedicated type for float4, leaving the vector type to
always represent a 3D vector, which will be done in a later commit.
This is not exposed to the user as a separate socket type with a
different color, it is only an internal type that uses the same vector
socket shape and color.
Since the vector socket represents both 4D and 3D vectors, code
generally assumes that such sockets represents 3D vectors, and the
developer is expected to set it to a 4D vector if needed in the node
operation constructor, or use the newly added skip_type_conversion flag
for nodes that do not care about types, like the File Output node.
Though this should be redundant once we add a dimension property for
vector sockets.

This patch uses OCIO luminance for implicit conversion from color to
float in the compositor. This is done to match other node systems, and
because luminance is a much better default than the average formula used
before.
Versioning was added to retain average conversion for old files.

This patch adds support for using integer sockets in compositor nodes.
This involves updating the Result class, node tree compiler, implicit
conversion operation, multi-function procedure operation, shader
operation, and some operations that supports multiple types.
Shader operation internally treats integers as floats, doing conversion
to and from int when reading and writing. That's because the GPUMaterial
compiler doesn't support integers. This is also the same workaround used
by the shader system. Though the GPU module are eyeing adding support
for integers, so we will update the code once they do that.
Domain realization is not yet supported for integer types, but this is
an internal limitation so far, as we do not plan to add nodes that
outputs integers soon. We are not yet sure how realization should happen
with regards to interpolation and we do not have base functions to
sample integer images, that's why I decided to delay its implementation
when it is actually needed.

By now it is just a "compositor", so move the files one folder up.
Things that were under realtime_compositor/intern move into
already existing intern folder.
