Fix memory leaking on ClosePage.chromium/2862
CFX_FontCache refactoring:
after this CL: Only one global CFX_FontCache used. Any cached items from it, are released, when its are not used.
BUG=79367,48791
The fonts was not cleared after unloading pages.
Test pdf:
http://www.nasa.gov/pdf/750614main_NASA_FY_2014_Budget_Estimates-508.pdf
For this file, we have ~5 fonts per page, which equal ~1 Mb per page.
In this PDF we have 670 pages, as result after slow scrolling(reading) full document we have ~600 Mb fonts data in memory.
memory usage of PDF Plugin:
before this CL: ~660 Mb
after this CL: ~100 Mb
