LOG: [lldb][test] Don't dead-strip WebAssembly test inferiors (#206799)

Unlike most native linkers, wasm-ld garbage-collects unreferenced
sections by default. Globals and functions that a test inspects but the
program never references therefore get dead-stripped from the inferior,
even though they would survive on other targets.

Default to `-Wl,--no-gc-sections` in WASI.rules so debug-info coverage
matches other targets.
