  Log Message:
  -----------
  [ADT] Refactor DenseMap::insert, try_emplace, and operator[] (NFC) (#155204)

try_emplace and operator[] contain nearly identical code, and the code
is duplicated for l-value and r-value reference variants.

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