  -----------
  [Clang][Sema]: Diagnose lambda to bool implicit casts (#83152)

Adds diagnostics for lambda expressions being cast to boolean values,
which results in the expression always evaluating to true.
Earlier, Clang allowed compilation of such erroneous programs, but now
emits a warning through `-Wpointer-bool-conversion`.

Fixes #82512
