Consistency tweak

- RENAMED: RayHitInfo to RayCollision
- RENAMED/REDESIGNED: Multiple Ray collision functions to be more consistent and return RayCollision data -WIP-

Added a simple cube with vertex colors for testing both.

Some breaking changes were introduced lately, it's better to note that current version is not 3.7 anymore...

Renamed for consistency with other function in raylib.

output->framePoses[frame] is over-allocated.
framePoses is a 2D array:
- first dimension: frames (allocated l. 4717)
- second dimension: nodes (allocated l. 4731)
Second dimension should be allocated of nodes_count transformations only.

boneWeights uint32 were loaded in normals instead of boneWeights.

REMOVED: DrawBillboardEx()

* Redesigned billboards - added rotation/pro functions

* updated parameters

Updated to fix versioning and linking issues.
Old version would cause examples to not be linked on fresh raylib install or linked with an old library version on updated raylib install.

* Added support for additional mouse buttons

* Renamed mouse button enum

Window shouldn't be considered ready when CloseWindow has been called.

This issue prevented enabling MSAA on several platforms

Now rlgl only depends on OpenGL and it's completely decoupled from platform layer libraries (EGL)

On PLATFORM_ANDROID, PLATFORM_RPI, PLATFORM_DRM and PLATFORM_UWP glfwGetProcAddress() is not defines, actually those platforms use egl platform windowing system.
