Jonas Devlieghere 88d2615129 [lldb] Add skipIfWasm decorator and skip unsupported WebAssembly tests (#194761)
Add a new `skipIfWasm` test decorator that skips tests on the "wasip1"
and "wasi" platforms, and apply it to the test classes that rely on
expression evaluation or lldb-server, neither of which is available when
debugging WebAssembly targets.
