Support building ash targets with use_ash=0 and use_aura=1.

Support building/running ash_unittests and ash_shell_with_content.
Change some build |use_ash| checks to |use_aura| (or remove them).

Avoid the unspecified ash dependency on chrome resources!
Explicitly load new ash_test_*.pak image/string resources instead.
(avoids including ash_resources in chrome paks w/use_aura builds)

Reserve more resource IDs for ash_strings to avoid overlap.
(uses 244 IDs now; reserve 300 instead of 200 to fit existing)
Reserve fewer content shell resource IDs, to avoid exceeding 3100.
(uses 4 IDs now; reserve 150 instead of 250 to keep current total)
https://code.google.com/p/chromium/codesearch#chromium/src/out/Debug/gen/content/shell/grit/shell_resources.h

Use base::i18n::GetConfiguredLocale(), in several ash_unittests.
(l10n_util::GetApplicationLocale fails IsLocaleAvailable('en-US'))
(because it's not loading the chrome locale data anymore)
(seems okay to pair with base::i18n::SetICUDefaultLocale)
