Config.pm - add taint_disabled and taint_support to %Config

This adds 'taint_disabled' and 'taint_support' to Config.pm and %Config.
This way people can use them while we decide what to do about the
changes to Configure. We shouldn't need to have Configure changed to
export status variables like this in Config.pm

See: https://github.com/Perl-Toolchain-Gang/Test-Harness/pull/118
and: https://github.com/Perl/perl5/pull/20972

for related work that is stalled because we have not decided what
to do about these variables.
