fix: have runTermElabM reset local context when types of autobound implicits contain metavariables (#7952) 
This PR makes two improvements to the local context when there are
autobound implicits in `variable`s. First, the local context no longer
has two copies of every variable (the local context is rebuilt if the
types of autobound implicits have metavariables). Second, these
metavariables get names using the same algorithm used by binders that
appear in declarations (with `mkForallFVars'` instead of
`mkForallFVars`).

This removes the last use of `Term.addAutoBoundImplicits'`, which
inherently has this variable duplication issue.
