Move core/fxge/ge to core/fxge.
This brings the cpp and h files together and removes the redundant ge/ path. Change-Id: I36594b8ae719d362768ba4c2e4ce173e287363eb Reviewed-on: https://pdfium-review.googlesource.com/7452 Commit-Queue: dsinclair <dsinclair@chromium.org> Reviewed-by: Tom Sepez <tsepez@chromium.org>
