[clang codegen] Fix MS ABI detection of user-provided constructors. (#90151)llvmorg-18.1.5
In the context of determining whether a class counts as an "aggregate",
a constructor template counts as a user-provided constructor.
Fixes #86384
(cherry picked from commit 3ab4ae9e58c09dfd8203547ba8916f3458a0a481)
