Add mulit format support to TimePicker

[NathanBP]

Allows format prop to allow an array of formats. The control then uses the array of formats when parsing a date from the input. The first value of the array determines the displayed format.

An example use case is that a user may want to enter a time as hmm but display as h:mm a.

Test which is failing is already failing in master branch. Once this is fixed this pull request will pass the required checks.
