WIP rcamera redesign vector (#2563)
* core functionality CAMERA_FREE

* fix example

* add remaining camera modes

* add view bobbing

* view bobbing

* catch curser in SetCameraMode

* adjust examples

* fix compilation on linux

* fix example text_draw_3d

* actually fix text_draw_3d

* Updated camera API

* Improve Vector3RotateByAxisAngle() function

* remove camera.mode dependency from low-level functions

* remove camera.mode from struct

* fixes after rebase

* adjust examples for new UpdateCamera function

* adjust example models_loading_m3d

/*******************************************************************************************
*
* raylib [models] example - loading gltf with animations
*
* LIMITATIONS:
* - Only supports 1 armature per file, and skips loading it if there are multiple armatures
* - Only supports linear interpolation (default method in Blender when checked
* "Always Sample Animations" when exporting a GLTF file)
* - Only supports translation/rotation/scale animation channel.path,
* weights not considered (i.e. morph targets)
*
* Example originally created with raylib 3.7, last time updated with raylib 4.2
*
* Example licensed under an unmodified zlib/libpng license, which is an OSI-certified,
* BSD-like license that allows static linking with closed source software
*
