Remove //components/favicon/core/browser

Remove //components/favicon/core/browser

This adds unnecessary complexity since only //chrome/browser uses
the favicon components and there are no other sub-directories in
//components/favicon/core.

This is a mechanical CL done using tools/git/move_source_file.py and then
changing the gyp/gn files to match.

jif: please take a look at the CL, in particular at gyp/gn files and
//components/favicon files

sky: TBR-ed as OWNERS of files impacted by the #include changes (mechanical)

reed: TBR-ed as OWNERS of //skia & //third_party/skia for the DEPS changes since
I'm moving the DEPS file from //components/favicon/core/browser to
//components/favicon/core
