egl/dri: flesh out and use dri2_create_drawable()

Wrap the loader->createNewDrawable() dance into a helper and use it
throughout the codebase.

This addresses a cases like surfaceless (SL) on swrast (SL on kms_swrast
is fine) where we'd attempt using the wrong driver and crash out.

v2: fixup quirky GBM (Mathias)
v3: fixup GBM for real (Marek)
