Revert to LIB_MODE=static for optimized builds (#11195) 

Summary:
Continuous performance testing indicates there's a small performance hit with shared library (-fPIC) builds, so while retaining the motivation for https://github.com/facebook/rocksdb/issues/11168, we set the default for DEBUG_LEVEL=0 Makefile builds back to LIB_MODE=static.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/11195

Test Plan: CI, with some updated checks and removal of some now obsolete LIB_MODE overrides
