  [C++20] [Modules] Keep DeductionGuideDecl in the general lookup table (#222246)

Close https://github.com/llvm/llvm-project/issues/222002

The root cause of the problem is, the deduction guide was not in the
general lookup table. The fix is to move them into the general lookup
table. This should be fine as the DeductionGuide may not pollute the
name lookup results.
