fix(cmake): reduce noise in debug build linker flags on Linux

Move optimization-focused linker flags to release builds only:
- --icf=safe: identical code folding for size optimization
- -O2: enable string tail merging optimization
- -z,combreloc: combine relocations for faster loading

Keep debugging-related flags in all builds:
- --compress-debug-sections=zlib: compress debug sections for smaller files
- --gdb-index: faster debug symbol loading in GDB

This reduces verbose linker output and link times in debug builds
while preserving essential debugging functionality.
