862715ea - Revert "[Clang] Instantiate local constexpr functions eagerly (#95660)" (#98991)

Revert "[Clang] Instantiate local constexpr functions eagerly (#95660)" (#98991) Unfortunately, #95660 has caused a regression in DeduceReturnType(), where some of the local recursive lambdas are getting incorrectly rejected. This reverts commit 5548ea34341e9d0ae645719c34b466ca3b9eaa5a. Also, this adds an offending case to the test. Closes #98526
