Several depth and color formats have been added for the framebuffer.
8-bit, 16-bit, and 24-bit formats are now available for depth.
RGB 8-bit (332), RGB 16-bit (565), and RGB 24-bit (888) formats are now available for color.
Alpha support is no longer present for the framebuffer at the moment, but it can easily be restored by adding the formats and reinterpolating the alpha in the areas that do not perform color blending.
Additionally, this commit brings performance improvements.
Also replace the triangle rasterization functions with macros that generate specific functions for each state of the rendering system.
Also, add the OpenGL definitions in order to add a binding for rlgl.
* [rcore] fix crash in InitWindow, due to unchecked result of InitPlatform
Check the result of InitPlatform(), if it isn't 0, report the Error
and return. This prevent crashes and allows for gracefully aborting
or recovering by checking IsWindowReady().
Partially-fixes: https://github.com/raysan5/raylib/issues/4801
* [rcore] style: store the result of InitPlatform() before checking it
Small style change that doesn't impact how the code behaves here.
Variable 'result' is not used anywhere else in this block,
it's just for compliance with Raylib's coding conventions.

* [rcore] use LOG_WARNING when InitPlatform() fails
...as this is preferred over LOG_ERROR.

In the case of a failure within miniaudio on the function: ma_convert_frames, the dynamic memory allocated for the `data` variable will leak on the early return.
