cmd/link/internal/ld: use 12.0.0 OS/SDK versions for macOS linking
Go 1.25 will require macOS 12 Monterey or later, so macOS 11 will be
unsupported. The comment here suggests using a supported macOS version,
and that it can be the most recent one.
For now, make a minimal change of going from 11.0.0 to 12.0.0 so that
the chosen version is a supported one (although not the most recent).
However, it looks like even in CL 460476 (where the comment was added)
we were staying with the macOS version that matched Go's oldest, so we
might not have have recent experience with going beyond that. Update
the comment accordingly.
For #69839.
