Remove dixRegisterPrivateOffset; hard-code devPrivates offsets instead

For predefined resource types, the offset of the devPrivates field was
already kept in a constant table. The only non-predefined type needing
this treatment was dbeDrawableResType, which is just a magic alias for
RT_PIXMAP.

This patch special-cases looking up RC_DRAWABLE offsets and uses the
table directly for everything else.
