Merge bitcoin/bitcoin#35937: test: Append print_suppressions=0 to LSAN_OPTIONS, and suppress bitcoin-qt

fad9ab714b test: Append print_suppressions=0 to LSAN_OPTIONS, and suppress bitcoin-qt (MarcoFalke)

Pull request description:

  (see commit msg for rationale and background).

  To test, one should be able to use the cmake options such as `-DCMAKE_C_COMPILER='clang' -DCMAKE_CXX_COMPILER='clang++' --preset=dev-mode -DBUILD_GUI=ON  -DSANITIZERS=address` on e.g. Fedora. Then see that the current suppressions file is insufficient, and also confirm that `print_suppressions=0` is required.
