Inline PL_no_symref_sv into its users. Deprecate the visible global variable.

As the core no longer needs this fixed string outside of pp.c, it seems daft to
make it public just in case any module wants to use it. Modules that do should
provide their own inline copy in future.

Also restore the visible global PL_no_symref_sv back to the original format
specificiation (of 5.10.0 and earlier).
