[wasm-split] Add a merge-profiles mode (#3917)
Given a list of profiles for the same module, --merge-profiles produces a single
combined profile the contains the minimum timestamp among the original profiles
for each function. When verbose output is enabled, also emit a message for each
profile that could individually be removed without affecting the set of
functions in the combined profile, as suggested in #3912.
