tpl: Fix metrics hint tracking

When tracking for cache hints, track the same template name as the call
to MeasureSince in Execute.  When referencing a partial "foo", the value
of `n` does not match `templ.Name()` (`partials/foo` versus
`partials/foo.html`).  This was causing hints to go untracked since
there was no existing metric to append the hint to.

Fixes #8125
