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
