chore(cli): Remove redundant CLI feature flags

The CLI previously had a bunch of feature flags, which were only left in
for legacy support, but which do not change behaviour anymore.

This commit removes the feature flags in question.

(flags: webc_runner, cache, wasi, debug, emscripten, cache-blake3-pure )

Closes #3954
