Daijiro Fukuda 7bb8ffc29e Win32: resolve some symbols re-definition of windows.h in glfw3native.h (#2643) 
* Win32: resolve some symbols re-definition of windows.h in glfw3native.h

This reflects GLFW's fix: https://github.com/glfw/glfw/issues/1348

This enables to build with a external GLFW containing the
following fix:

* 05f6c13d11

Currently, glfw3native.h of the internal GLFW is customized at
2feea87b61

This fix is compatible with the current customized glfw3native.h.

This fix enables us to update it to the latest and remove the
customization.

* Win32: remove unneeded typedef

/**********************************************************************************************
*
* rcore - Basic functions to manage windows, OpenGL context and input on multiple platforms
*
* PLATFORMS SUPPORTED:
* - PLATFORM_DESKTOP: Windows (Win32, Win64)
* - PLATFORM_DESKTOP: Linux (X11 desktop mode)
* - PLATFORM_DESKTOP: FreeBSD, OpenBSD, NetBSD, DragonFly (X11 desktop)
* - PLATFORM_DESKTOP: OSX/macOS
* - PLATFORM_ANDROID: Android (ARM, ARM64)
* - PLATFORM_RPI: Raspberry Pi 0,1,2,3 (Raspbian, native mode)
* - PLATFORM_DRM: Linux native mode, including Raspberry Pi 4 with V3D fkms driver
* - PLATFORM_WEB: HTML5 with WebAssembly
*
* CONFIGURATION:
*
* #define PLATFORM_DESKTOP
* Windowing and input system configured for desktop platforms: Windows, Linux, OSX, FreeBSD, OpenBSD, NetBSD, DragonFly
* NOTE: Oculus Rift CV1 requires PLATFORM_DESKTOP for mirror rendering - View [rlgl] module to enable it
*
* #define PLATFORM_ANDROID
* Windowing and input system configured for Android device, app activity managed internally in this module.
* NOTE: OpenGL ES 2.0 is required and graphic device is managed by EGL
*
* #define PLATFORM_RPI (deprecated - RPI OS Buster only)
* Windowing and input system configured for Raspberry Pi in native mode (no XWindow required),
* graphic device is managed by EGL and inputs are processed is raw mode, reading from /dev/input/
* WARNING: This platform is deprecated, since RPI OS Bullseye, the old Dispmanx libraries are not
* supported and you must be using PLATFORM_DRM
*
* #define PLATFORM_DRM
* Windowing and input system configured for DRM native mode (RPI4 and other devices)
* graphic device is managed by EGL and inputs are processed is raw mode, reading from /dev/input/
*
* #define PLATFORM_WEB
* Windowing and input system configured for HTML5 (run on browser), code converted from C to asm.js
* using emscripten compiler. OpenGL ES 2.0 required for direct translation to WebGL equivalent code.
*
* #define SUPPORT_DEFAULT_FONT (default)
* Default font is loaded on window initialization to be available for the user to render simple text.
* NOTE: If enabled, uses external module functions to load default raylib font (module: text)
*
* #define SUPPORT_CAMERA_SYSTEM
* Camera module is included (rcamera.h) and multiple predefined cameras are available: free, 1st/3rd person, orbital
*
* #define SUPPORT_GESTURES_SYSTEM
* Gestures module is included (rgestures.h) to support gestures detection: tap, hold, swipe, drag
*
* #define SUPPORT_MOUSE_GESTURES
* Mouse gestures are directly mapped like touches and processed by gestures system.
*
* #define SUPPORT_TOUCH_AS_MOUSE
* Touch input and mouse input are shared. Mouse functions also return touch information.
*
* #define SUPPORT_SSH_KEYBOARD_RPI (Raspberry Pi only)
* Reconfigure standard input to receive key inputs, works with SSH connection.
* WARNING: Reconfiguring standard input could lead to undesired effects, like breaking other running processes or
* blocking the device if not restored properly. Use with care.
*
* #define SUPPORT_BUSY_WAIT_LOOP
* Use busy wait loop for timing sync, if not defined, a high-resolution timer is setup and used
*
* #define SUPPORT_PARTIALBUSY_WAIT_LOOP
* Use a partial-busy wait loop, in this case frame sleeps for most of the time and runs a busy-wait-loop at the end
*
* #define SUPPORT_EVENTS_WAITING
* Wait for events passively (sleeping while no events) instead of polling them actively every frame
*
* #define SUPPORT_SCREEN_CAPTURE
* Allow automatic screen capture of current screen pressing F12, defined in KeyCallback()
*
* #define SUPPORT_GIF_RECORDING
* Allow automatic gif recording of current screen pressing CTRL+F12, defined in KeyCallback()
*
* #define SUPPORT_COMPRESSION_API
* Support CompressData() and DecompressData() functions, those functions use zlib implementation
* provided by stb_image and stb_image_write libraries, so, those libraries must be enabled on textures module
* for linkage
*
* #define SUPPORT_EVENTS_AUTOMATION
* Support automatic generated events, loading and recording of those events when required
*
* DEPENDENCIES:
* rglfw - Manage graphic device, OpenGL context and inputs on PLATFORM_DESKTOP (Windows, Linux, OSX. FreeBSD, OpenBSD, NetBSD, DragonFly)
* raymath - 3D math functionality (Vector2, Vector3, Matrix, Quaternion)
* camera - Multiple 3D camera modes (free, orbital, 1st person, 3rd person)
* gestures - Gestures system for touch-ready devices (or simulated from mouse inputs)
