Paul Duffin 51084ff6cf Add //visibility:override to allow control over inheritance
Visibility rules can be 'inherited' in one of two ways. Either from
defaults or from a module that called ctx.CreateModule(...).
Previously, in both cases the inheriting module could only append
additional visibility rules to the end of the inherited rules. That
made it impossible to restrict the visibility by removing or ignore
inherited rules.

The //visibility:override rectifies that by allowing the inheriting
module to ignore all the rules that they would have inherited. It can
only go at the beginning of a list of rules specified in a module but
after defaults are applied it can end up in the middle of a list of
rules. In that case it behaves as if all the rules up to and including
the //visibility:override rule were discarded.

It can be used with //visibility:private to override
//visibility:public and vice versa.
