Stabilize -Z symbol-mangling-version as -C symbol-mangling-version

Browse source 
This allows selecting `v0` symbol-mangling without an unstable option.
Selecting `legacy` still requires -Z unstable-options.

Continue supporting -Z symbol-mangling-version for compatibility for
now, but show a deprecation warning for it.
