egl: Fix _eglModeLookup.

Internally a mode belongs to a screen.  But functions like
eglGetModeAttribMESA treat a mode as a display resource: a mode can be
looked up without a screen.  Considering how KMS works, it is better to
stick to the current implementation.

To properly support looking up a mode without a screen, this commit
assigns each mode (of all screens) a unique ID.
