Just for a better consistency

Exposing internal memory allocator/free, useful for advance users when required

Pefixing/Suffixing some data type identifier in the variables is not a convention used in raylib, just reviewed it for consistency...

Still, I kept the *Rec suffix in some functions.

Previous implementation did not consider any padding while drawing the characters on screen (despite being available on the font atlas), so, only minimum character area was drawn.

If some text effect shader was required (shadow, glow, outline...), there was no space in the drawn quad to draw that pixels effect.

This commit corrects that issue.

This is a BREAKING CHANGE!

To address the linked issue, several functions have been renamed and couterpart functions have been created to free loaded memory:
 - RENAMED: GetImageData() -> LoadImageColors()
 - RENAMED: GetImagePalette() -> LoadImagePalette()
 - RENAMED: GetWaveData() -> LoadWaveSamples()
 - ADDED: UnloadImageColors()
 - ADDED: UnloadImagePalette()
 - ADDED: UnloadWaveSamples()

Previous GetKeyPressed() method was actually returning unicode codepoints equivalent values instead of the key-code of the pressed key. So, it has been replaced by GetCharPressed(), returning unicode codepoints and GetKeyPressed() now returns key-codes.

* Changed extension for web from .bc to .a

I did this to support vcpkg expectation. When using the library from vcpkg for web you would install it using vcpkg install raylib:wasm32-emscripten but also vcpkg expects the output lib to be with .a extension instead of .bc

Doesn't make a difference for standalone builds or when raylib is used as a subdirectory dependency.

* Added headers to install targets to fix vcpkg usage

Currently vcpkg works by installing the cmake target into its packages directory. The problem is that install only copies the public header at this point so we need to add the others to the install targets.
