BLI code for enums that are meant to be used as "bit flags" defined
an ENUM_OPERATORS macro in BLI_utildefines.h. This cleans up things
related to said macro:
- Move it out into a separate BLI_enum_flags.hh header, instead of
"random bag of things" that is the current place,
- Update it to no longer need manual indication of highest individual
bit value. This originally was added in a31a87f89 (2020 Oct), in
order to silence some UBSan warnings that were coming
from GPU related structures (looking at current GPU code, I don't
think this is happening anymore). However, that caused actual
user-visible bugs due to incorrectly specified max. enum bit value,
and today 14% of all usages have incorrect highest individual
bit value spelled out.
- I have reviewed all usages of operator ~ and none of them are
used for directly producing a DNA-serialized value; all the
usages are for masking out other bits for which the new ~
behavior that just flips all bits is fine.
- Make the macro define flag_is_set() function to ease check of bits
that are set in C++ enum class cases; update existing cases to use
that instead of three other ways that were used.

Recursive downsample was only used by workbench DoF
which can be expressed using mip view instead.
The mip render workaround was creating GL error on startup
and is not needed anymore.

This PR adds a clear on creation for draw region framebuffers, which
fixes issue https://projects.blender.org/blender/blender/issues/139443.
When using the "Lock Interface" option, redrawing is disabled until the
rendering process has finished. When the GPU driver does not initialize
framebuffer textures with zero, this means that visual corruption can
be perceived when resizing the main window while rendering.
This fix makes sure that framebuffer textures are initialized with zero
on all GPU platforms.
