Log Message:
-----------
MouseEvent offsetX and offsetY should be relative to padding edge

rdar://125763807
Reviewed by Abrar Rahman Protyasha.
This patch aligns WebKit with Gecko / Firefox and Blink / Chromium.
Merge:
https://chromium.googlesource.com/chromium/src.git/+/ad76338520534c07a557bb68db876fbf2c34ce49
Currently, we are computing relative to target coordinate while we should
be relative to padding box and this patch subtract borderLeft / borderTop
from offsetX / offsetY to achieve this. This matches us with the web
specification [1] & [2]:
[1] https://drafts.csswg.org/cssom-view/#dom-mouseevent-offsetx
"...return the x-coordinate of the position where the event occurred relative
to the origin of the padding edge of the target node..."
[2] https://drafts.csswg.org/cssom-view/#dom-mouseevent-offsety
"...return the y-coordinate of the position where the event occurred relative
to the origin of the padding edge of the target node..."
