* examples: Add imageformats example
Example which renders RGBA color wheel, alpha gradient and full value channel textures to
catch conversion errors and bad internal type representations between different backend
renderers.
The example uses bimg to convert from a master texture to different textures.
Each texture is rendered in an ImGui list using `ImGui::Image`. A close-up is visible
when hovering over each image.
U and I textures are skipped because they don't work for sampling.
Compressed textures are skipped because they don't have conversion functions.
Depth textures are not rendered because they don't work with channels.

* Minor rewording & increase of clarity
* Corrected a noun that was being used as a verb
* Slight rewording of the C99 bindings notices
* Actually, this sounds better & looks nicer
Current docs are a little ambiguous with the term "profiling"; sometimes it means
bgfx::CallbackI functions, and sometimes per-view stats collection. This makes it a little clearer.
Adds support on tools.mk for the msys2 environment. The OS is still
considered windows but the command line tools for mkdir and rmdir
behave as if on linux.
The variable SHADER_TMP on the makefiles also had to be quoted to make
it work on msys2.
This echo command on the makefile behaves differently between linux and gnuwin32:
```
-@echo extern const uint8_t* $(basename $(<))_pssl;>> $(@)
```
On linux the semicolon immediately ends the echo command and its output is never piped to the embedded shader's header.
If you try to fix it by quoting the string:
```
-@echo "extern const uint8_t* $(basename $(<))_pssl;" >> $(@)
```
It will work on linux but not on gnuwin32 because the quotes will appear on the outputted string.
The solution was to use printf which works consistently between the two.
Also on gnuwin32 the outputted string has 'CRLF' line endings, which clashes with the rest of the 'LF' line endings
of the embedded shaders header which were produced by shaderc.
The solution was to remove the 'CR' from the outputted string by using the tr command.
In non-embedded shaders there is a separation between essl binaries (examples/runtime/shaders/essl)
and glsl binaries (examples/runtime/shaders/glsl). On embedded shaders there is no such separation
and by default essl shaders are being used by the OpenGL runtime. This usually doesn't cause any
issues but in the case of the debugdraw shaders, that started using uvec4, this now leads to a
runtime error. This patch fixes this by splitting the embedded shaders into essl and glsl.
As asked, this is the first part of the change.
To be able to compile the 'examples/common/debugdraw' shaders, pull
request #2362 is needed.
* Fix typo in SPIR-V id
* Use backend-agnostic shaderc output
...as opposed to directly storing and comparing against Vulkan and WebGPU enums. This is backwards-compatible with existing code and shaders.
* Remove comments and Undefined value
