acceleration, lens length, and power
`TEMPERATURE` type was also missing, not only the new-ish
`TIME_ABSOLUTE` one...
Added a static assert on the size of the `bpyunits_ucategories_items`
array, and a comment on anonymous enum of `B_UNIT_`, in the hope this
won't happen again in the future.

python API
Adds an example python script to the documentation for the 3D_IMAGE shader.
The **use-case** is to draw textures with 3D vertex positions, in XR views as well as non-XR views (in a simpler manner).
**Testing**: I've tested that this compiles and works on my Macbook (with the example python script included in this change). I don't have access to a Windows or Linux machine right now, but this change doesn't look platform-specific and no new glsl shaders have been added or edited by this change. I'll try to get access to a Windows machine, but if someone does have one, I'd be really grateful if they could try this change. Thanks!
**Problem addressed**: The existing 2D_IMAGE shader (exposed in the python API) gets near-clipped when drawn in the
XR view, regardless of the near-clip settings. Additionally, the 2D_IMAGE shader only accepts 2D
positions for the image vertices, which means drawing textures in 3D requires providing
2D coordinates and then pushing a transform-rotate-scale matrix to the GPU, even for
non-XR (i.e. WINDOW) views. The 3D_IMAGE shader is simpler: it accepts 3D vertex positions, and doesn't require
any additional work by the scripter.
**Workaround**: The current workaround is to use custom shaders in the python script.
**Non-intrusive change**: No new glsl shaders were added. This change just bundles two existing shaders: the vertex shader used
by the 3D_IMAGE_MODULATE_ALPHA shader, and the fragment shader used by the 2D_IMAGE shader.

Related to T95616, the relationship between Image ID and ImBuf 'cached'
buffers can be fairly confusing when using the RNA API.

The previous docs for `normal_update` methods of `BMVert`, `BMEdge`,
`BMFace`, and `BMesh` were not clear on some behaviors. These
behaviors are listed in D14370. This commit updates the docs to be
clearer.

Regression caused by [0] that caused the error message to be
created based on a normalized exception (which hid line numbers).
PyC_ExceptionBuffer{_Simple} & BPy_errors_to_report
no longer clears the exception.
This could have been resolved by changing python_script_error_jump
however that would involve changes to reference counting that are more
risky (noted in code-comment).

Add missing check as the context override dict may have been copied
since it was assigned, also initialize the context manager with
PyType_Ready, while it didn't cause any errors - it's expected
that all types are initialized.

As `GPU_PRIM_LINE_LOOP` is not supported on Vulkan or Metal and
`GPU_PRIM_TRI_FAN` is not supported on Metal, they will be removed in
future releases.
So it is important to inform users that they are obsolete and may not
be supported for a long time.

The "PROP" in the name reflects its generic status, and removing
"LOOP" makes sense because it is no longer associated with just
mesh face corners. In general the goal is to remove extra semantic
meaning from the custom data types.

- Increase the stack level so the reported line number references

Support a way to temporarily override the context from Python.
- Added method `Context.temp_override` context manager.
- Special support for windowing variables "window", "area" and "region",
other context members such as "active_object".
- Nesting context overrides is supported.
- Previous windowing members are restored when the context exists unless
they have been removed.
- Overriding context members by passing a dictionary into operators in
`bpy.ops` has been deprecated and warns when used.
This allows the window in a newly loaded file to be used, see: T92464

having to extract and type-check them separately.

Since shader sources are now parsed on demand via `GPUShaderCreateInfo`,
sources are not available to be read via
`GPU_shader_get_builtin_shader_code`.
Currently this results in a crash as the code tries to read `NULL`
pointers.
`GPU_shader_get_builtin_shader_code` was created with the intention of
informing the user how a builtin shader works, thus "replacing"
detailed documentation.
Therefore this function doesn't really have a practical use in an addon.
So, instead of updating the function (which would require several
changes to the gpu module), remove it and improve the documentation.

Python exceptions are now shown in the info editor,
this also resolves an old bug where errors were printed twice.
This was originally based on D9752 by @ShadowChaser although many
changes have been made from the original patch.
Details:
- BPy_errors_to_report no longer prints additional output.
- BKE_report_print_test was added so it's possible to check if calling
BKE_report also printed to the stdout.
- Callers to BPy_errors_to_report are responsible for ensuring output
is printed to the stdout/stderr.
- Python exceptions no longer add a trailing newline,
needed to avoid blank-space when displayed in the info-editor.
