I wouldn't say "no concrete implementation is provided" because it is a concrete implementation, it just does not perform locking.
"No-op implementation of locks for the WebAssembly System Interface. The implementation does not need to perform locking, because as of <insert WebAssembly spec version, or today's date> WebAssembly does not support threads."

Since WebAssembly doesn't support threading, no locking is done in runtime. This PR adds a no-op implementation in
MutexWASI.hto improve compatibility with WASI.This is a part of SR-9307 and #24684.
