  [Clang] [Sema] Combine fallout warnings to just one warning (#127546)

This merges several falloff and noreturn-related warnings and
removes unused diagnostic arguments.

Changes:
- `warn_maybe_falloff_nonvoid_function` and
`warn_falloff_nonvoid_function`, `warn_maybe_falloff_nonvoid_coroutine`
and `warn_falloff_nonvoid_coroutine`,
`warn_maybe_falloff_nonvoid_lambda` and `warn_falloff_nonvoid_lambda`
were combined into `warn_falloff_nonvoid`,

- `err_maybe_falloff_nonvoid_block` and `err_falloff_nonvoid_block` were
combined into `err_falloff_nonvoid`

- `err_noreturn_block_has_return_expr` and
`err_noreturn_lambda_has_return_expr` were merged into
`err_noreturn_has_return_expr` with the same semantics as
`warn_falloff_nonvoid` or `err_falloff_nonvoid`.

- Removed some diagnostic args that weren’t being used by the diagnostics.
