73c18fb668 Sema: Better distinguish scalar from variadic generic argument positions, and reject pack expansion types there 
We used to disallow pack expansions in generic argument lists of
protocols, but allow them for all other nominal types. However,
we only actually checked that the pack expansions match up if
the type itself was variadic.

Fix this by repurposing Context::ProtocolGenericArgument into
Context::ScalarGenericArgument, and using that when the type does
not have a parameter pack.

Context::GenericArgument is now Context::VariadicGenericArgument,
and we only use it if the type has a parameter pack, in which case
we use the PackMatcher, so any pack expansions in the wrong place
are caught there.

Fixes rdar://116716014 and https://github.com/apple/swift/issues/69088.

3e436d316f Sema: Fix two problems in checkReferencedGenericParams() analysis 
- Don't walk into the count type of a PackExpansionType, because
  when matching two PackExpansionTypes, the solver only introduces
  a shape constraint between the count types, which does not fix it
  to a concrete type.

- Similarly, don't walk into type alias substitutions, because
  only the desugared type is considered by the constraint solver.

This is mildly source breaking, in that before we let you declare
generic functions that could not be called.

89ad597fe3 Sema: Use getAllMembers() from collectVisibleMemberDecls() 
I had to disable typo correction in one test case to get it to pass without
diagnosing a cycle as a result of Sendable checking. But that's OK, because:

- Sendable checking is prone to request cycles and needs to be redesigned
- Typo correction is turned off in production
