fix(datepicker): inconsistent focus restoration timing in touchUi mode #17732

Merged

MatDatepicker has focus restoration which happens (almost) synchronously, whereas MatDialog restores focus asynchronously when the animation is finished. This means that in touchUi mode focus ends up being restored both by the datepicker and the dialog within a 150ms window. The problem is that if the consumer of MatDatepicker decides to move focus inside the closed event, it'll be ovewritten by the dialog 150ms later. These changes disable the dialog's focus restoration because it's unnecessary.

Fixes #17560.

@crisbeto Sorry, looks like I forgot to review this one. LGTM as long as you're able to rebase it
