Fix T89984: Improve Icon previews reflective and transmissive materials.

Before this commit rendering material icons the floor will is hidden.
This reduces the readability of reflective/refractive materials.

check patch for additional screenshots and notes.

This patch will switch the floor material that uses ray visibility tricks to render a floor for reflective rays.

Eevee uses screen space reflections that makes this a different problem. There is nothing else drawn in
the scene in screen space so we need a different trick. Using math we convert a reflective ray to UV space
and generate a world that projects a checker pattern to infinity.

As now the floor is in the world it is being reflected via
a cubemap. As the film is transparent the background (including the floor isn't rendered)

In the future when Eevee supports vulkan raytracing we can re-evaluate and perhaps remove this
approximation.

We tried lightprobes but that wasn't able to do the trick.
Using the compositor would lead to more memory usage (render layers and intermediate buffers) and slower performance.
Solution has been validated with Simon

BLF: Do Not Cache Unused Rendered Glyphs

The loading of a font size or style renders bitmaps of the characters
0-255 and stores them in a cache. But glyphs 128-255 in this cache are
not accessible. What used to be ansi high-bit characters are now multi-
byte UTF-8 sequences.

Therefore this patch reduces the glyph_ascii_table size to 128 and
only caches characters 32-127, the visible portion of ASCII, which
greatly reduces the time to load a font.

See D12189 for more details.

Fix: DNA struct alignment on 32 bit

Some of the dna structs were not properly
aligned for 32 bit builds causing issues

Makesdna: Fix detecting 32 bit padding issues.

Makesdna fails to detect issues in 32 bit code that can
only be resolved by adding a padding pointer.

We never noticed since we ourselves no longer build for
32 bit, but debian's 32 bit builds got bitten by this

A rather extensive explanation on why this is alignment

Fix T90630: Crash loading certain user preferences

Clearing the window was done in wm_file_read_post which was deferred.

Fix T88386: Continuous Grab occasionally jumping on Arm64 MacOS

During the processing of a continuous drag event, other mouse move
events may be in the queue waiting to be processed.

But when a mouse wrapping happens, these waiting mouse move events
become out of date as they report a mouse position prior to wrapping.

The current code ignores these events by comparing their `timestamp` to
the time recorded in the last mouse wrapping.

The bug happens because the computed value in
`mach_absolute_time() * 1e-9` for some reason is incompatible with the
value of `[event timestamp]`.

Since macOS 10.6, we have a new way to get the amount of time the
system has been awake. `[[NSProcessInfo processInfo] systemUptime]`.

Using this updated method fixed the problem.

Compositor: Full frame input nodes

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.
