LOG: [lldb][test] Skip stop-reason tests unsupported on WebAssembly (#211266)

TestThreadStates::test_process_state expects a signal stop reason after
"process interrupt", but the trap from the single step used to step off
the breakpoint is reported as a trace stop. It is already skipped on
Linux and Darwin for the same reason.

TestBuiltinDebugTrap expects to continue past __builtin_debugtrap, but
on WebAssembly that lowers to the unreachable instruction, a fatal trap
that cannot be resumed.
