Mofei Zhang 00a53cc3bd [compiler] Collect temporaries and optional chains from inner functions
Recursively collect identifier / property loads and optional chains from inner functions. This PR is in preparation for #31200

Previously, we only did this in `collectHoistablePropertyLoads` to understand hoistable property loads from inner functions.
1. collectTemporariesSidemap
2. collectOptionalChainSidemap
3. collectHoistablePropertyLoads
    - ^ this recursively calls `collectTemporariesSidemap`, `collectOptionalChainSidemap`, and `collectOptionalChainSidemap` on inner functions
4. collectDependencies

Now, we have
1. collectTemporariesSidemap
    - recursively record identifiers in inner functions. Note that we track all temporaries in the same map as `IdentifierIds` are currently unique across functions
2. collectOptionalChainSidemap
    - recursively records optional chain sidemaps in inner functions
3. collectHoistablePropertyLoads
    - (unchanged, except to remove recursive collection of temporaries)
4. collectDependencies
    - unchanged: to be modified to recursively collect dependencies in next PR
