Currently there are a few callbacks on `bNodeType` that do the same
thing for every node type except reroutes and frame nodes. Having a
callback for basic things complicates code and makes it harder to
understand, and reroutes and frames are special cases in larger way.
Arguably frame nodes shouldn't even be drawn like regular nodes,
given that it adds a case of O(N^2) looping through all nodes.
"Unrolling" the callbacks makes it easier to see what's happening,
and therefore easier to optimize.

This helps to tell when a pointer is expected to be null, and avoid
overly verbose code when dereferencing. This commit also includes
a few other cleanups in this area:
- Use const in a few places
- Use `float2` instead of `float[2]`
- Remove some unnecessary includes and old code
The change can be continued further in the future.
Having settings such as "extend" saved between executions causes
keymaps that don't include this setting to remember the value
between execution.
No longer store this setting for selection operations & remove
redundant values from the key-maps, see: T90275.
While this was already the case for the most part
some selection operators stored common settings for reuse such as
"toggle", "extend" & "deselect".
Disabling storing these settings for later execution
as it means failure to set these options in the key-map re-uses
the value of the shortcut that was last called.
Skip saving these settings since this is a case where reusing them
isn't helpful.
Resolves T90275.
This adds a viewer node similar to the one in the compositor.
The icon in the headers of nodes is removed because it served
the same purpose and is not necessary anymore.
Node outputs can be connected to the active viewer using
ctrl+shift+LMB, just like in the compositor. Right now this collides
with the shortcut used in the node wrangler addon, which will
be changed separately.
As of now, the viewed geometry is only visible in the spreadsheet.
Viewport visualization will be added separately.
There are a couple of benefits of using a viewer node compared
to the old approach with the icon in the node header:
* Better support for nodes that have more than one geometry output.
* It's more consistent with the compositor.
* If attributes become decoupled from geometry in the future,
the viewer can have a separate input for the attribute to visualize.
* The viewer node could potentially have visualization settings.
* Allows to keep "visualization points" around by having multiple
viewer nodes.
* Less visual clutter in node headers.

This just moves a couple of files in `space_node` to C++ and fixes
related errors.
The goal is to be able to use C++ data structures to simplify the code.
