Subsurf: Remove edit mesh modifier callbacks

Those were used for partial updates during edit mode, which will
not be possible anymore with OpenSubdiv.

Optimization for OpenSubdiv would be to re-use topology refiner
if topology does not change. But this is something to be done
for both edit and object modes, no need to have separate code
paths for those.

This commit makes OpenSubdiv to properly work in edit mode.

Fix Python warnings when running in background.

Cleanup: fix compiler warnings.

GP: Add layer pass index to time modifier

Fix: buffer overflow when creating gpu.types.GPUIndexBuf

GP: Add new modes to Time Offset modifier

GPUShader: shader.uniform_float, matrix parsing

Add checks to parse 3x3 or 4x4 matrices,
also use error from `mathutils_array_parse` instead of overwriting.

Partially revert "GPUShader: shader.uniform_float parameters"

`mathutils_array_parse` is meant to parse 1d arrays of numbers.

Using matrices internal memory layout is confusing since
mathutils matrices are exposed as row major.

Also, the matrix shape wasn't checked for.

Callers that want to handle matrices should check for them explicitly.

I18n: tweak/fix exception catching code of pgettex() wrapper.

Related to T57066, rather unlikely to fix core of the issue, but may
solve crash itself.

Same as rBf22385f28ec8 (did it by mistake in 2.8 first :/ ).

Fix T57351: Deform modifiers skipped in editmode

Fixup for LATTICE_OT_flip

Committed by accident (1076523b1b62a3d8833bf2a).
But now I need to fix building.

Note: The operator itself shouldn't have been committed because it
should operate in the world space (for the axis), not local.

I will tackle this later.

Silence some false positiver warnings

Cleanup: use bmesh index access functions
