[clang] [Sema][NFC] Move two misplaced uninit tests to clang/test/SemaCXX (PR #128013)

[Donát Nagy via cfe-commits]

https://github.com/NagyDonat created https://github.com/llvm/llvm-project/pull/128013

Because they are the last two remaining test files that appeared under `clang/test/Analysis` but were unrelated to the clang static analyzer. For background see the following discourse thread: https://discourse.llvm.org/t/taking-ownership-of-clang-test-analysis/84689/2

I placed them in in `clang/test/SemaCXX` because they are testing the `-Wuninitialized` warning family and the other tests of this feature can be found there (or in `Sema`, `SemaObjC` depending on the language).

Note that `clang/test/Analysis` contains many other test files named `uninit-*`, but those test the uninitialized value handling of the clang static analyzer, which is independent of the (non-path-sensitive) compiler warnings that are tested in the two files that I'm moving.

Also note that the implementation of the `-Wuninitialized`-like warnings relies on the source files `clang/lib/Analysis/UninitializedValues.cpp` and `clang/lib/Sema/AnalysisBasedWarnings.cpp`, and this would theoretically justify leaving their tests in the "Analysis" directory; but in practice the "Analysis" directory is almost exclusively used by the static analyzer, so I still decided to relocate these two tests for the sake of consistency.
