`GetFileSize()` conflicts with the infamous `windows.h`

Previously failed to build with an implicit declaration of `_NSGetExecutablePath`.

Unless these imports require to have this format, the code has been adjusted to the conventions

* Fix a signature error with the windows calls in GetApplicationDirectory for 32 bit builds.

* break is better than loop var to -1

* Fix formating problems with GetApplicationDir.
Don't ever return an empty string

* always return a valid path even if it's ./

* remove the need for the dll and just use the normal GetModuleFileName function

* Add a function to return the application directory.

* CI fixes

The previous implementation somewhat break the expected behaviour for games and examples when pressing the `Fullscreen` button in the provided `shell.html`.

Just reverted for the moment for further investigation.

* Added drawing text with shadow

* Added SetWindowOpacity()

* Edited Mis-spell

* Fixed conventions

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

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

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

Register keys independently of the actions

This function is not required, users can check it with `GetGamepadName()`

* - support create OpenGL debug context in OpenGL 4.3

* - additional events in debug message
- fixed glEnable(GL_DEBUG_OUTPUT)

* Reviewed OpenGL Debug Context

Those defines are only used inside `rlgl` module
