Revert of Move file_handlers API from //chrome to //extensions

Revert of Move file_handlers API from //chrome to //extensions (patchset #5 id:80001 of https://codereview.chromium.org/2685453002/ )

Reason for revert:
Broke compile on Linux x64. Example failure: https://build.chromium.org/p/chromium.chrome/builders/Google%20Chrome%20Linux%20x64/builds/16205

The build error is kind of confusing to me so apologizes in advance if this is the wrong CL.
