GPencil: Cleanup unused code

The poll method is not used

Viewport: support dropping object-data to create instances

This allows orphan object data for example (meshes, curves, etc)
to be dropped into the 3D View from the outliner,
creating a new object instance.

Previously the only way to do this was to add the same type of object
then swap it's data through the ID selector drop-down.

Fix T75827, boolean of non-manifold objects leaves stray edges.

Well, this only fixes the example if one uses the new Exact mode,
but since that is available, seems fair to call this fixed.
Since these were not closed-volume operands, the Exact mode needed
some adjustment to the threshold used for "inside-outside" tests
for the case of deciding if the cutter is inside the other shape
for a Difference.

GLState: Use unsigned long long instead of unsigned long for shifts

This fix a compilation warning on msvc.

Cleanup: clang-format

Cleanup: spelling

Makefile: update spell checking targets

Update check_spelling targets to match changes to the utility,
take an optional CHECK_SPELLING_CACHE argument.

Fix T67265: Status bar is overlapped by workspace layout

The issue was that the screen geometry calculations scaled down the
areas, but the header would become too small. So it would be upscaled
again towards the lower screen edge (where the status-bar is at). Now we
do another pass over the geometry calculations, until all areas fit into
the screen, or until some rather arbitrary maximum is reached.

This fixes the issue for common cases. Extreme cases, with many
vertically stashed editors and a too small window to show all, are still
not too well supported. Blender keeps working but the status-bar is
still overlapped. We could deal with this better but what's there now
should be good enough.

Cleanup: Add const to BKE screen function

GLState: Fix compilation warning on MSVC

GLTexture: Fix undefined behavior when binding textures the first time

GLDebug: Trim NVidia debug output

These buffer detailed infos are not needed unless going deep into
perf. profiling, in which case you can still disable this compile option.

This makes user report log much more readable.

GLTexture: Add Feedback loop check

The check is better than before as we take into
consideration the attached mip level.

Cleanup: GPUFramebuffer: Remove unused variable

GLTexture: Add direct state access support

GLState: Add texture multibind and remove redundant binds

Math Utils: Add bitscan 64bit version

GPUTexture: OCIO: Workaround new missing bind error checking

We cannot change the texture bind point since the interface count
4/5 textures to bind. Changing the uniform to avoid one bind
make the system thinks one texture is missing.

Avoid this by creating a dummy texture and binding it to the empty
slot.

GPUDebug: Only enable resource checking in debug mode

Cleanup: GPUTexture: Move debug messages outside of creation function
