This is to modernize the API:
- Add meaningful name to all textures (except DRW textures).
- Remove unused err_out argument: only used for offscreen python.
- Add mipmap count to creation functions for future changes.
- Clarify the data usage in creation functions.
This is a cleanup commit, there is no functional change.

- Move gpuPush/Pop from GPU_draw.h into GPU_state.h
as this is for pushing/popping state.
- Add 'GPU_STANDALONE' define, to bypass use of user-preferences
for theme colors and pixelsize, as well as pbvh init/free functions.
Needed to get GHOST tests working again.
The current code allocates and transfers a lot of memory to the GPU,
but only a small portion of this memory is actually used.
In addition, the code calls many costly gl operations during the
caching process.
This commit significantly reduce the amount of memory by allocating
and transferring a flat array without pads to the GPU.
It also calls as little as possible the gl operations during the cache.
This code also simulate a billinear filter `GL_LINEAR` using a 1D texture.

Two main reasons for the lag:
- Allocation of memory with transfer to GPU.
- BLF_cache_clear();
The (partial) solution is to avoid memory allocating in some setups
through the `GPU_texture_clear`.

The memory allocation seems to be unnecessary, so I removed it.

Functions that utilize glyph cache should lock and unlock cache by
calling `blf_glyph_cache_acquire()` and `blf_glyph_cache_release()`.
Function `blf_glyph_cache_acquire()` will create glyph cache, if it doesn't exist.
Locking mutex is global and shared by all fonts.

We do not support special color fonts (like colored emoji fonts), so
don't crash when trying to create a preview for unsupported fonts.

There are two issues at play here.
First, BLF_width computed a width that was not wide
enough to actually hold the text.
Second, blf_glyph_calc_rect_test computed an incorrect
rect->xmax when the glyph was moved to the left a bit.
We ignore the overlap on the left, but the right side
should still be adjusted accordingly.
The main problem was that the character `J` has "negative kerning".
It was cut off because it started outside of the clipping rectangle.

- BEGIN/END license blocks
Developers should add non license comments as separate comment blocks.
No need for separator text.

This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.
See P901 for script to perform these edits.
This changes the text hinting setting to be an enum with options
Auto / None / Slight / Full. The default is Auto which currently disables
hinting.
The hinting was tested with a new FreeType version, but this is not what
is used on the buildbots an official release environment, and the fonts
look quite bad because of that. Once FreeType has been upgraded we can
change the default.
Even then the results are not ideal, perhaps due to missing subpixel
positioning and linear color blending support in BLF.
- Texture creation now requires explicit data type.
- GPU_texture_add_mipmap enable explicit mipmap upload.
- GPU_texture_get_mipmap_size can be used to get the size of a mipmap level
of an existing GPUTexture
- GPU_texture_read let you read back data from a gpu texture.
In an effort to centralize all opengl calls in the codebase, this patch replaces
the raw opengl calls in bf_blenfont with GPUTexture so it's no longer depended
on opengl headers.
