feature-microblaze-versions.inc: Clean up and consolidation

Clean up the MicroBlaze versions tunes as well and improve the
TUNECONFLICTS for version features so that the conflicts matrix is
automatically generated. Additionally consolidate the version features
into a single include.

Improve and generate the "-mcpu=" and package strings based on the
version feature.
