eglfs: Add a way to force 24/32 bit configs
Some embedded devices do not play nicely with 16-bit (565)
EGL configurations, resulting in ugly banding in Quick apps.
Add a QT_QPA_EGLFS_FORCE888 environment variable that can be
set on systems where it is known that only 24 or 32 bit configs
provide acceptable results.
