Bug 1238160 - Set docshell isolation mode. r=smaug

Browse Source 
Renames nsDocShell isBrowser* attributes to add a "Moz" prefix for clarity.

Adds nsDocShell::GetIsIsolatedMozBrowserElement, which parallels
GetIsInIsolatedMozBrowserElement, but only checks the immediate docshell.

Adds nsDocShell::SetIsInIsolatedMozBrowserElement for the frame loader and tab
child to set the isolation state.

nsDocShell methods related to mozbrowser elements (and their callers) are
updated to use GetIs(In)?IsolatedMozBrowserElement when checking isolation /
origins and GetIsMozBrowserElement when checking frame types.
