Can this fail; do we need to nullptr-check the result of GetCount()?

[We really should upgrade this library to llvm::Expected<> at some point]

6.2 cherry-pick of #81299.
Description: Remote mirrors did not support types containing parameter packs. Add that support.
Scope of the issue: This meant that parameter packs defeat lldb's remote mirrors-based code path, forcing the ASTContext to be loaded. This should no longer be necessary.
Risk: There is a bunch of new code, and it might have bugs in it. However this doesn't change behavior of existing code.
