builder: add strlen to wasm builtins

Browse Source 
LLVM 22 can replace string-scanning loops with calls to strlen during
optimization. Add the implementation to wasmbuiltins and invalidate
cached archives.

Add an optimized wasm-unknown smoke test that exercises the reflect
name-decoding path which exposed the missing symbol.
