Cleanup: rename namespace TimeIt to timeit

According to our style guide, namespaces should have
lower case names.

BLI: refactor how buffers for small object optimization are stored

Previously, there was an error when operator-> was returning an
invalid type. See error C2839.

UV: add rip tool

New rip tool matching edit-mesh rip functionality.

Useful as disconnecting UV's, especially for loops is inconvenient
without this.

This uses 'V' to rip, changing stitch to 'Alt-V'.

BMesh: add BM_face_calc_uv_cross

BMesh: add BM_loop_other_vert_loop_by_edge

Fix T78481: Workbench Shadow effects XRay

When in XRay some effects (shadow, cavity & depth of field) aren't supported.
This patch makes sure that these effects aren't enabled.

Cleanup: warnings, spelling

BLI: improve exception safety of memory utils

Even if we do not use exception in many places in Blender, our core C++ library
should become exception safe. Otherwise, we don't even have the option
to work with exceptions if we decide to do so.

GPU: Remove local shaders workaround for Intel/Windows

It has been tested that local shaders workaround isn't needed for the
latest Windows/Intel 6xx GPU's.

Currently the local shaders workaround doesn't work anymore during the
investigation it was detected that the intel drivers didn't need it
anymore.

Local shaders should still be fixed as it is also used for some legacy
iGPU's. The current work around crashes when doing preview renders in
EEVEE as the default materials aren't available but for the work around
they should. (See T77346 for more information)

Revert "BLI: refactor how buffers for small object optimization are stored"

This reverts commit 5d79f9f276b4b3e6289308c534c58e7ee3bb5e2d.

Logic to determine if the library icon should be used was too general.

Cleanup: Fix small typo error

GPencil: Cleanup some comments typo
