* Implementing GetMonitorWidth/Height and GetMonitorPhysicalWidth/Height for drm

Added implementation for DRM for functions :
 - GetMonitorWidth()
 - GetMonitorHeight()
 - GetMonitorPhysicalWidth()
 - GetMonitorPhysicalHeight()
 - GetMonnitorName()

These functions take an argument but only the value 0 is accepted. This is because the DRM platform implementation manages only one screen for now

* Refactor "GetMonitor" properties for DRM Platform

Refactored GetMonitorHeight, GetMonitorWidth, GetMonitorPhysicalHeight,
GetMonitorPhysicalWidth and GetMonitorName to accept only argument "0"
as more than one screen is not supported in DRM platform.

* Rework window placement and dimensions for multi-monitor setups;

- fullscreen apps use primary monitor, exclusively
- non-fullscreen apps come in two variants:
a) pre-determined window size by user
b) use-active-monitor dimensions by user specifying 0x0
Either way, the window shall be centred at the monitor where it was created

This may have been the original intent, yet the primary monitor was used also for the second case, regardless where the window opened.

* Clean up code, handle error, fix integer-overflow for centering windowed fullscreen

They need to be exposed on `rlgl.h` header section (not implementation section) because with some specific use cases (custom config.h, rmodels module enabled), building fails otherwise.

Redesigned function to only consider separation between the end of vertical size of one line and the beginning of next line

The `RL_CULL_DISTANCE_` definition remains as the initial value
of the variables.

Basic usage can be:
```c
#include <raylib.h>
#include <rlgl.h>

rlSetClipPlanes(RL_CULL_DISTANCE_NEAR, MY_CULL_DISTANCE_FAR);

if (must_reset_clip_planes)
    rlSetClipPlanes(RL_CULL_DISTANCE_NEAR, RL_CULL_DISTANCE_FAR);
```

* Fix several non-functional `target_compile_definitions`

* Avoid hardcoding the default vertex attribute locations

* Implement functional `rlNormal3f`

* Add normal definitions for `DrawCube`

* Update the basic lighting example to use `DrawCube` and `DrawPlane`

* Remove support for 0.11.0, and make build script more idiomatic
+ remove all 0.11.0 compatibility functions
+ remove most LazyPath .path variants
  + I didn't touch emscripten, I don't know if its relative or absolute
+ change all absolute paths to use .cwd_relative
+ only use the builder allocator
+ have local dependencies use the package manager
+ make adding raygui more flexible
+ use zig-cache for generated wayland files

* Remove support for 0.11.0 in examples/build.zig

* update examples further and add clarifying comment on addRaygui

Support all JOINT formats supported by glTF specs

* Flip release of buffer;

First it needs to be taken out of the processing chain, then it can be released. The inverse of the initialization.

* Add mutex locks to audio buffer functions; Separate those used from both threads

* Flip release of buffer;

First it needs to be taken out of the processing chain, then it can be released. The inverse of the initialization.

* Remove TODO marker; The buffer is in stopped state and its data won't be accessed

* Add mutex locks to music/stream functions directly operating on buffer

* Secure UpdateMusicStream/PlayMusicStream/UpdateAudioStream;

This change is twofold:
* Add locks to UpdateMusicStream/UpdateAudioStream (second one needed separation)
* Remove unnecessary hack to restart music - inlining the statements resulted in a no-op

Especially the second part made it easier to ensure thread-safety overall

* Remove redundant check; Already checked at beginning of function

This could be actually very tricky and GPU/drivers dependant...

For consistency, now _almost_ all `Draw*Lines()` functions use `RL_LINES` mode for drawing. It solves the linked issue but it can have other implications, as mentioned in the WARNING comment in `DrawRectangleLines()`.

Side note: `DrawRectangleRoundedLines()` now should be reviewed for consistency.

- Review formatting
 - Improve readability for some functions result return
 - Minimize early returns
 - Align LoadFileData() to UnloadFileData()

The way the current code worked was by calling `GetCurrentMonitor()`,
which would always return the monitor at position (0,0). This isn't the
primary monitor on all platforms, on Linux in particular it isn't the
case.

This isn't the case on the SDL backend, after calling `InitWindow()` the
window would always show up on the primary monitor. Even on the GLFW
backend, if the full screen flag was set it would attempt to put it on
the primary monitor as it would call `glfwGetPrimaryMonitor()` to do it,
so for consistency's sake we should do it on windowed mode too.
