Attempt to reduce the binary size due to fmtlib

[Anilm3]

Changes:

• Set FMT_OPTIMIZE_SIZE to reduce the size of fmtlib (also removes locale-specific code).
• Add format.cc to reduce inlining.
• Move templates from utils.hpp to utils.cpp and instantiate for specific type.
• Move functions from semver.hpp to semver.cpp.
• Enabled LTO on MacOS builds.
