Pepper: Remove Will* from PPB_FileIOTrusted.

Nobody uses these methods today. Additionally, WillWrite/WillSetLength are no
good for plugin-side writes. They require an extra IPC round-trip that has to
be made for every write call. I don't see any advantage of this over a plugin
just calling Write()/SetLength() directly and getting a NOQUOTA error back.

I'm removing these methods to clean up code a bit and make the FileIO move from
the renderer to the browser smaller.
