  [NFC][CLANG] Fix null pointer dereferences (#86760)

This patch replaces getAs<> with castAs<> to resolve potential static
analyzer bugs for

1. Dereferencing Proto1->param_type_begin(), which is known to be
nullptr
2. Dereferencing Proto2->param_type_begin(), which is known to be
nullptr
3. Dereferencing a pointer issue with nullptr Proto1 when calling
param_type_end()
4. Dereferencing a pointer issue with nullptr Proto2 when calling
param_type_end()

in clang::Sema::getMoreSpecializedTemplate().
