cmd/link: put read-only data in __DATA_CONST segment On darwin, we put read-only data in __TEXT segment on AMD64 in exe (non-PIE) buildmode, and in __DATA on everywhere else. This is not ideal: things in __DATA segment are not read-only, and being mapped R/W may use more run-time resources. In fact, newer darwin systems support a __DATA_CONST segment, which the dynamic linker will map it read-only after applying relocations. Use that. Fixes #38830.
