Internal, renderer and UI changes + 1.19-pre1 support

Minecraft 1.19 support:
- Since 1.19-pre1, LWJGL 3.3.1 is used. However, LWJGL 3.2.3 still works with it, at least for this Minecraft release.
- Added a hack to skip calling to ObjC codes (skipped an asset file to skip setting the icon)
- JNA version replacing: now only change to 5.8.0 if version < 5.8.0

Internal changes:
- Cleanup: moved global functions to a new place
- Handle demo user correctly: actually authenticate the game with demo's access token and use the Xbox gamertag as the username
- Start moving strings to Localizable.strings (WIP)
- Re-wrote the Microsoft authentication and account management to Objective-C
- Assets downloading: added a tiny sleep call so that the UI won’t be frozen when too many tasks are executed at the same time

Renderers changes
- gl4es: `init_constructor` is now enabled, therefore moved the preload part to before `eglInitialize` (or EGL will be de-init after gl4es's hardware test).
- gl4es-extra (aka holy gl4es 1.1.4) is now used to replace the regular gl4es. This fixes VBO issue on version < 1.13 and some extra stuff. https://github.com/PojavLauncherTeam/gl4es-114-extra/commit/d6cf5c4
- Removed gl4es 1.1.5 and `Disable gl4es shaderconv` as it's unnecessary for now
- Removed vgpu, as it requires some missing extensions when come to shaders

User interface:
- The account selection list now displays the skin head (or the Xbox gamerpic if demo) and the account type
