gallium/util: revert util_format_init addition

Putting calls to util_format_init all over the codebase is infeasible.

Instead, half float tables are pregenerated, and the s3tc library is
loaded on demand.

I believe this is a solution that combines performance, cleanliness,
flexibility and portability.
