Refactor CFX_FontCache to have only one in GE Module.
After this CL: only one global CFX_FontCache used. Any cached items from it, are released, when they are not being used. This is restore part of reverted CL: Original CL: https://codereview.chromium.org/2158023002 Revert reason: BUG=647612 Fix bug CL: https://codereview.chromium.org/2350193003 Review-Url: https://codereview.chromium.org/2350243002
