feat(Input): Ability to specify an Input ErrorComponent

[markrickert]

Motivation

I have this patched locally on rc.7 mainly so that I can animate the text in and out when shown.

I included a component in the example that shows how to animate error messages, which was not possible with the current errorMessage implementation.

Fixes n/a

Type of change

• New feature (non-breaking change which adds functionality)

How Has This Been Tested?

• Jest Unit Test
• Checked with example app

Additional context

I had trouble committing because of the pre-commit hook. yarn lint-staged was failing for me so skipped the hooks. If this doesn't build/run on CI, please let me know what I can do to get it passing.

Locally, with these changes, yarn && yarn lint && yarn typescript && yarn test all run locally.
