Allow silent extension installations from the extensions gallery - Part 1.

In this episode we:
-Create a new ChildProcess privilege (SILENT_INSTALL_EXTENSION) which is granted to the extension gallery pages.
-Ensure that extension gallery pages are isolated into their own process which is never shared with other urls.

Important: The SILENT_INSTALL_EXTENSION privilege is never granted any additional abilities in this patch, so this patch only has the effect of grouping gallery URLs into a separate process.

In subsequent patch(es) we plan to (a) observe this new privilege and allow gallery urls to install extensions bypassing the normal prompts, (b) polish this UI flow [in particular, do not show the black "loading" dilaog, (c) check the id of the extension to be installed (from the crx) matches the expected id (from gallery url).
