  [ADT] Refactor MapVector::insert, try_emplace, and operator[] (NFC) (#155205)

The l-value and r-value reference variants of try_emplace contain
nearly identical code.  Also, operator[] makes its own call to
Map.try_emplace.

This patch introduces a templated helper function, try_emplace_impl,
and uses it in all of MapVector::insert, try_emplace, and operator[].
The helper function uses perfect forwarding to preserve the exact key
type.

This patch moves the "private:" section to the end of the class so
that the new helper function can use iterator.
