Revert of Pdfium: Fix fonts leaking on ClosePage. (patchset #10 id:180001 of https://codereview.chromium.org/2158023002/ )
Reason for revert:
Causes heap-use-after-free. See crbug.com/647612.
Original issue's description:
> Fix memory leaking on ClosePage.
> 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
>
> Committed: https://pdfium.googlesource.com/pdfium/+/cde5101eb15b24519e89fa500fe37038bc8e2201
