Needed when rendering cursers which (unlike framebuffers)
actually are transparent.

egl_texture_blit() blits a texture, simliar to egl_fb_blit() but by
rendering the texture to the screen instead of using a framebuffer blit.
egl_texture_blend() renders a texture with alpha blending, will be used
to render the cursor to the screen.

Add helper function to import a dma-buf as opengl texture.
Also add a helper to release the texture again.

Rename the functions to to say "setup" instead of "create" because they
support being called multiple times on the same egl framebuffer.
Properly delete unused textures, update function interfaces to support
this.

Add a collection of egl_fb_*() helper functions to manage and use opengl
framebuffers, which is a common pattern in UI code with opengl support.

When running on gtk we need X11 platform not mesa platform.
Create separate functions for mesa and x11 so we can keep
the egl #ifdef mess local to egl-helpers.c

Leftover from the early opengl days.
Unused now, so delete the dead code.

Unfortunaly switching to getPlatformDisplayEXT isn't as easy as
implemented by 0ea1523fb6703aa0dcd65e66b59e96fec028e60a. See the
longish comment for the complete story.

According to
https://www.khronos.org/registry/EGL/extensions/MESA/EGL_MESA_platform_gbm.txt
if MESA_platform_gbm is supported display should be initialized
from a GBM handle using eglGetPlatformDisplayEXT.

Re-run scripts/clean-includes to apply the previous commit's
corrections and updates. Besides redundant qemu/typedefs.h, this only
finds a redundant config-host.h include in ui/egl-helpers.c. No idea
how that escaped the previous runs.
Some manual whitespace trimming around dropped includes squashed in.
