Fix Android keycode translation and duplicate key constants

[M374LX]

Fixes #3729
Fixes #3734

All of the keys I am able to test are correct. However, I cannot test the keypad (because I use a tenkeyless keyboard), the keyboard menu key (because my keyboard lacks it) and the Android menu key (because my phone lacks it and also because of #3734). Additionally, the Super (Windows) and Print Screen keys are grabbed by the system and apparently cannot be caught by the app.

Note: there seems to be an issue (already present, not introduced by this PR) in which the app freezes on Android if a keyboard is connected after the app starts. For this reason, I recommend testers to connect a keyboard and force stop the test app before starting it (fixed by including keyboard in the manifest's android:configChanges).

Update: with 1df491c, #3734 is also fixed, but it introduces a breaking change, as the value of KEY_MENU is changed.

Code example

#include <raylib.h>
#include <stdio.h>

static const char* get_key_name(int key);

int main()
{
	int last_key = 0;

	InitWindow(800, 600, "Android Keyboard Test");

	while (!WindowShouldClose()) {
		int pressed_key = GetKeyPressed();
		char str[64] = "";

		if (pressed_key != KEY_NULL) {
			last_key = pressed_key;
		}


		BeginDrawing();
		ClearBackground(GRAY);

		sprintf(str, "%d - %s", last_key, get_key_name(last_key));
		DrawText(str, 16, 16, 32, BLACK);

		sprintf(str, "%d", (int)GetTime());
		DrawText(str, 16, 64, 32, BLACK);

		EndDrawing();
	}

	CloseWindow();

	return 0;
}

@M374LX Thanks for the review with the Android keycodes remap. Just noted that latest keycodes.h includes about 316 possible keys... but no need to add them all to the mapping right now.

About the breaking change... I think we can assume that risk...
