Manuel Stoeckl f5df956c18 render/gles2: add a few 10-bit and FP16 formats 
The half-float formats depend on GL_OES_texture_half_float_linear,
not just the GL_OES_texture_half_float extension, because the latter
does not include support for linear magni/minification filters.

The new 2101010 and 16161616F formats are only available on little-
endian builds, since their gl_types are larger than a byte and thus
endianness dependent.

Manuel Stoeckl 44e8451cd9 render/gles2: hide shm formats without GL support 
This change introduces a new function to check whether the renderer
has the needed GL extensions to read a given pixel format.

Simon Ser f76960388f render/gles2: add support for some 24 and 16-bit formats 
On little-endian, we can enable pixel formats which don't use
gl_type = GL_UNSIGNED_BYTE. See [1].

render/gles2: remove assumptions about supported formats 
We were assuming GL_BGRA_EXT was always supported.

We now check that it's supported for rendering. We fail if it isn't because
this format is specified as "always supported" by the Wayland protocol.

We also check if it's supported for reading pixels. A new preferred_read_format
function returns the preferred format that can be used to read pixels. This is
used by the screencopy protocol.

Backport screenshooter fixes from the renderer redesign v1 
This backports some changes to #319 to fix the screenshooter data
format. This also adds wlr_backend_get_renderer which will be
useful to support multiple renderers.
