commit 92e7407c76710e17382408458c711d10f1b6bef8

Format-as-you-type for the phone number in web payments UI on desktop.

Before this patch, typing "3103106000" into a phone number field in web
payments UI on desktop would leave the field as-is, which is difficult
to read.

This patch extends ValidationDelegate to also handle text field
formatting. Formatting happens only when the user is typing at the end
of the field or when user has left the field (blur). Typing in the
middle of the field does not cause reformat because Views does not have
functionality to position the cursor, which is required to make
auto-formatting feel natural.

After this patch, typing "3103106000" into a phone number field in web
payments UI on desktop will format-as-you-type this number into "+1
310-310-6000".
