Remove PNaCl's RequestFirstInstall, use resource throttle instead
This removes PNaCl's RequestFirstInstall and its use of
the component updater OnDemand API. A different CL:
https://codereview.chromium.org/
25713007/
will do the OnDemand calls internally.
This removes the async IPCs, callbacks, and observers that
were used to support the old code. The new code just
throttles/blocks the pexe URL request until OnDemand
installation is done.

other CLs.
