f6ba26ff58 render/gles2: implement texture_from_buffer 
Make it so wlr_gles2_texture is ref'counted (via wlr_buffer). This
is similar to wlr_gles2_buffer or wlr_drm_fb work.

When creating a wlr_texture from a wlr_buffer, first check if we
already have a texture for the buffer. If so, increase the
wlr_buffer ref'count and make sure any changes made by an external
process are made visible (by invalidating the texture).

When destroying a wlr_texture created from a wlr_buffer, decrease
the ref'count, but keep the wlr_texture around in case the caller
uses it again. When the wlr_buffer is destroyed, cleanup the
wlr_texture.

69d4cf19b5 render/gles2: assert texture comes from the same renderer 
Rendering a wlr_texture with a different wlr_renderer is invalid.
Add an assert to make sure this doesn't happen.

Make it clear GLES2 is being used. Before this commit, various
GL-related information was printed, but not an easy-to-find line
about which renderer is being picked up.

9f012cac2f drm: check for PRIME support 
PRIME support for buffer sharing has become mandatory since the renderer
rewrite. Make sure we check for the appropriate capabilities in backend,
allocator and renderer.

1cdef8da57 render: drop wlr_renderer_blit_dmabuf 
It can be replaced with wlr_renderer_bind_buffer. blit_dmabuf is
broken as-is (dies on an assertion).

9601a2abf0 output: improve transform matrix calculation 
Compute only the transform matrix in the output. The projection matrix
will be calculated inside the gles2 renderer when we start rendering.

The goal is to help the pixman rendering process.

bfd020047d render/gles2: remove current_buffer checks

afdf4dc890 render/gles2: make EGL context current in bind_buffer 
Instead of requiring callers to manually make the EGL context current
before binding a buffer and unsetting it after unbinding a buffer, do
it inside wlr_renderer_bind_buffer.

This hides renderer-specific implementation details inside the
wlr_renderer interface. Non-GLES2 renderers may not use EGL.
This removes all EGL dependencies from the backends.

render/gles2: save/restore EGL context in destroy_buffer 
It can be surprising that destroying a buffer changes the EGL context,
especially since this can be triggered from anywhere wlr_buffer_unlock
is called.

Prevent this from happening by saving and restoring the EGL context.

26af316b3b render/gles2: make wlr_gles2_texture_from_* private 
These functions are unused by compositors (see e.g. [1]) and prevent
wlr_gles2_texture from accessing wlr_gles2_renderer state. This is an
issue for proper teardown [2] and for accessing GLES2 extensions.
