Riteo 7e0f7d3abd Add Wayland support 
Not everything is yet implemented, either for Godot or personal
limitations (I don't have all hardware in the world). A brief list of
the most important issues follows:

- Single-window only: the `DisplayServer` API doesn't expose enough
information for properly creating XDG shell windows.

- Very dumb rendering loop: this is very complicated, just know that
the low consumption mode is forced to 2000 Hz and some clever hacks are
in place to overcome a specific Wayland limitation. This will be
improved to the extent possible both downstream and upstream.

- Features to implement yet: IME, touch input, native file dialog,
drawing tablet (commented out due to a refactor), screen recording.

- Mouse passthrough can't be implement through a poly API, we need a
rect-based one.

- The cursor doesn't yet support fractional scaling.

- Auto scale is rounded up when using fractional scaling as we don't
have a per-window scale query API (basically we need
`DisplayServer::window_get_scale`).

- Building with `x11=no wayland=yes opengl=yes openxr=yes` fails.

This also adds a new project property and editor setting for selecting the
default DisplayServer to start, to allow this backend to start first in
exported projects (X11 is still the default for now). The editor setting
always overrides the project setting.

Special thanks to Drew Devault, toger5, Sebastian Krzyszkowiak, Leandro
Benedet Garcia, Subhransu, Yury Zhuravlev and Mara Huldra.

// OpenXR requires us to submit sRGB textures so that it recognizes the content
// as being in sRGB color space. We do fall back on "normal" textures but this
// will likely result in incorrect colors as OpenXR will double the sRGB conversion.
// All major XR runtimes support sRGB textures.
// In OpenGL output of the fragment shader is assumed to be in the color space of
// the developers choice, however a linear to sRGB HW conversion can be enabled
// through enabling GL_FRAMEBUFFER_SRGB if an sRGB color attachment is used.
// This is a global setting.
// See: https://www.khronos.org/opengl/wiki/Framebuffer
// In OpenGLES output of the fragment shader is assumed to be in linear color space
