Make some Dictionary code smaller (dotnet/coreclr#10993)

Store a reference to the relevant entry at the start of the loop to avoid indexing `entries` multiple times.
This avoids some redundant range checks in `Remove` and allows the elimination of a duplicate `index++` in `Enumerator.MoveNext`.

Saves ~7KB of code.
