Enable the RenderViewTest printing tests on the Mac.

Migrates some test APIs from wstring path names to FilePath objects, and fixes some gcc compilation issues, to allow the tests to build on Mac.

Moves rendering logic and some other pdf logic into PdfMetafile to avoid duplication with unit test code. Switches rendering from the deprecated CGContextDrawPDFDocument to the newer (but less convenient) CGContextDrawPDFPage.

Added debugging helpers to PdfMetafile: SaveTo, matching the other platform metafiles, and context retain count checking to get early warning of issues that will cause printing failure.

BUG=24750
TEST=N/A
