Wayland: Add support for fractional scaling

Browse Source 
This adds basic support for fractional-scale-v1.

Note that this introduces a potential discrepancy between window and
monitor content scales.

GLFW uses the [fractional-scale-v1][] protocol to implement fine-grained
framebuffer scaling. If the running compositor does not support this protocol,
the @ref GLFW_SCALE_FRAMEBUFFER window hint will only be able to scale the
framebuffer by integer scales. This will typically be the smallest integer not
less than the actual scale.
