Raising priority to p1 because the from the latest build, the chrome.dwp execeeds the 4GB limit.

As a workaround, we want to set remove_webcore_debug_symbols=true in release buidls for arm.

This is listed as a CrOS Infra problem, but the CrOS Infra team
is likely poorly placed to solve this, and really, I think this
is a product problem.

Passing to snanda@ in hopes he can find a better owner.

chromeos-chrome: remove webcore debug symbols on arm.

The size limit of elf32 is 4GB, and the size of .dwp has exceeded this
limit. As a result, the .dwp is corrupt and we could not get any symbols
from it. This CL removes the debug symbols of webcore as a workaround
and we need to fix this in other ways.

BUG= chromium:792999 
TEST=the new .dwp file is 2.8 GB.

Webkit: keep minimal symbols when remove_webcore_debug_symbols is set.

We want to keep minimal symbols when remove_webcore_debug_symbols is
set, so that we can get readable backtrace.

On ChromeOS arm build, the size of debug file increases from
899MB to 1.244GB. It increases 245 MB.

chrome_sdk: Keep debug symbols for webcore on simple chrome.

We plan to use another gn parameter in the ebuild to reduce the
size of debug files of webcore on arm. So we need to override
the option to make simple chrome unaffected.

BUG= chromium:792999 
TEST=simple chrome works with this change.

R65 may need the changes otherwise there is no valid stack trace of webcore on arm.
