1. [BUGFIX lts] Fixes ArrayProxy length reactivity …

   Recent refactors for performance left a gap in the reactivity model,
   specifically for the `length` property of ArrayProxy. We now only use
   the `CUSTOM_TAG_FOR` API when getting chain tags, which is much better
   for most `get()` usages since we don't have to do an extra brand check
   that is not very commonly used. However, the `length` property of
   ArrayProxy does not have a normal property tag, and it is a native
   getter which does not entangle the value naturally when accessed via
   autotracking.
   
   This PR sets up the `length` tag eagerly whenever the content of the
   ArrayProxy changes, and consumes it when the `length` property is
   accessed. It also does the same thing for the `arrTag`, though that is
   only used for chain tags. Normally, when the array tag is accessed, it
   tracks things properly through the `objectAt` API.
