* Fixed functions Vector2Angle and Vector3Angle

* typo

* Unrolled everything.

Following the pattern in Vector3Normalize.

functions use radians, making this awkward to use.

Allow to choose which modules are compiled with raylib, if some modules are excluded from compilation, required functionality is not available but smaller builds are possible.

* Expose GetRenderWidth and GetRenderHeight functions

* Fix scissor on macos

* Fix typo

if `BUILD_LIBTYPE_SHARED` is defined allow build as a shared dll

* Override CC while compiling for ANDROID_ARCH x86

* REfix Override CC while compiling

Allow texture loading with no data transfer (in case image.data = NULL)

MAX_DIRECTORY_FILES macro removed.
ClearDirectoryFiles() tweaked to reflect changes.

Now that 4.3 was added this can be enabled with the compile flag.

- All variables are initialized on declaration, some arrays were not properly initialized
 - Static array buffers require memset() for re-initialization on every function call

NOTE: New raylib release installer uses `w64devkit`, smaller and more updated than regular `mingw64-w64` default project. Paths are updated properly.
