add a linux_use_debug_fission gyp variable for -gsplit-dwarf
Since -gsplit-dwarf breaks some extremely useful build tools (eg ccache and icecc), it deserves its own gyp variable. This setting replaces the previous hack, setting binutils_version=0.
Background:
ccache: https://bugzilla.samba.org/show_bug.cgi?id=10005
icecc: https://github.com/icecc/icecream/issues/86
BUG=352046
Review URL: https://codereview.chromium.org/226613005
git-svn-id: svn://svn.chromium.org/chrome/trunk/src@267381 0039d316-1c4b-4281-b951-d872f2087c98
