fix(input): use Chromium's email validation regexp

This change uses the regexp from Chromium/Blink to validate emails, and corrects
an error in the validation engine, which previously considered an invalid email
to be valid. Additionally, the regexp was invalidating emails with capital
letters, however this is not the behaviour recomended in the spec, or implemented
in Chromium.

Closes #5899
Closes #5924
