Cleanup: remove unused panel SEQUENCER_PT_sound

These have since been moved to SEQUENCER_PT_source.

WM: Add 'Confirm On Release' option for WM_OT_radial_control

Adds a new property called "Confirm On Release" that does what it says,
confirm the action without having to do left-click or to press any other
extra-key which concludes in a more dynamic and efficient way of changing
brush size or strength for example, especially for tablet users.

PyAPI: use PyModule_AddType utility function

Cleanup: clang-format, spelling

Fix finding system Haru library on Debian.

Paths and names of system packages-installed libhpdf on Debian (and
probably its derived distributions?) are slightly different than what
was given to CMake finding script.

Mesh automated testing: improve progress printing

Print number of total tests with each test to show how many tests have been executed and how many are left.
Example: `Running test 27/36: PlaneFaceSplitByEdges...`

Mesh automated testing: compare selection

MeshTest now compares selection between evaluated mesh and expected mesh. This way, we can test more operators
such as `faces_select_linked_flat`

Note: selection comparison intentionally does not happen in BKE_mesh_cmp() on C side but rather on Python side, because
selection is independent of mesh generation.

GPU Python: GPUOffScreen refactor

Remove "unbind" method.

Move context creation to your own class:
```
"__enter__", "__exit__" moved to "GPUOffScreenStackContext"
```

GPU Python: Implement new object type 'gpu.types.GPUUniformBuf'

For use by `gpu.types.GPUShader` only.

The API of this object includes:
```
>>> gpu.types.GPUUniformBuf.
free(
update(
```

GPU Python: Implement new object type 'gpu.types.GPUFrameBuffer'

For framebuffer operations on the GPU.

The API of this object includes:
```
>>> gpu.types.GPUFrameBuffer.
__enter__(
__exit__(
bind(
clear(
free(

GPU Python: Implement new object type 'gpu.types.GPUTexture'

This object allows you to do some simple operations with Textures on the GPU.

Can also be used for `gpu.types.GPUShader`.

It will be important to implement `gpu.types.GPUFramebuffer`.

The API of this object includes:
```
>>> gpu.types.GPUTexture.
clear(

This was just a copy and paste error / typo. The proper DNA variable
wasn't used. Thanks @charlie for finding the issue.
