Add temporary CHECKs in ICU init to attempt to more closely locate crash

Add temporary CHECKs in ICU init to attempt to more closely locate crash

At the moment it CHECKs on false return from base::i18n::InitalizeICU.
Try to locate it to a particular failure in that function to have a
better idea what's failing.

One very unlikely possibility (because we're all using wchar for paths, etc,
this should not be an issue) is that somewhere we messed up a path. I guess you
have a similar concern, which is what you want to catch with these checks.

That's possible. I'm not sure if we'll learn much from these checks, but I'm
hoping it will give us a better guess.

The theory that seems the most plausible to me is heavy fragmentation/low
memory, so mapping the file is not possible. But the crash rate seems too high
for that? So maybe not.

It looks like android_webview_unittests fails to map the data file. Do you
expect to happen?
