This patch aligns WebKit with Gecko / Firefox and Blink / Chromium.

Merge: https://chromium.googlesource.com/chromium/src.git/+/040a94e06971c4272408375ea1cffe1aeae2a316

This PR enables `input` number type to output value after decimal input
rather than 'emptyString'. This doesn't affect `value` content attribute and
`value` IDL attribute.
