Avoid clamping zero text size to 12pt in FontPlatformData::setupPaint() in FontPlatformDataLinux.cpp
Set all metrics to 0 if the font size is specified as zero in SimpleFontDataChromiumWin.cpp, just
like Safari Win did in r72270.

WebKitTools: update-webkit-support-libs should fall back to existing
WebKitSupportLibrary version if there is no internet connectivity
https://bugs.webkit.org/show_bug.cgi?id=49503

Fall back to existing support libraries (if present) when there is
no internet connection.

Currently, update-webkit-support-libs dies with an "out-of-date"
error when there is no internet connection because it cannot
retrieve versioning information from developer.apple.com. Because
update-webkit-support-libs fails, build-webkit fails. Instead,
if there is no internet connection and the support libraries are
present then we should warn the user and exit() with success so
that build-webkit can work without an internet connection.
