If you pass a string from script to an IDL method that takes an nsIAtom,
XPConnect will automagically atomize the string for you.

But nsIAtom is no longer scriptable (see the blockers for bug 1392883,
especially bug 1396694). So the code to convert can be removed.

This tests both that the settings have the desired effect and that switching
between sharing enabled and sharing disabled without a startup cache flush
does not cause any issues.

Tests for user pref changes are currently non-fatal, since they're known not
to work reliably.

User preference changes currently don't reliably take effect before component
loader initialization, which means they can't be used to write reliable tests.
Environment variables don't have this problem, so adding an environment
variable override makes testing much easier. It's also fairly convenient
during development, when we need to switch between different configurations
for testing.

Scripts for use in shared globals need to be compiled for non-syntactic
scopes, while scripts for standalone globals should be compiled as global
scripts for better performance.

Since the startup cache and script preloader store scripts as they were
compiled in the last session, when global sharing settings may have been
different, it can lead to a mismatch, and a crash, due to loading the wrong
type of script.

Using a separate cache path for each type of script fixes this problem, since
it ensures that the cached script will always be of the type we expect.

When we pre-compile scripts for a different global than they are eventually
executed in, we need to clone them into the new global before we can execute
them, which can be expensive. This also prevents us from using lazy parsing,
since lazy functions are currently eagerly compiled when cloned.

Since the vast majority of the scripts compiled by the preloader are executed
in the shared modules scope, initially compiling them there removes a lot of
startup overhead. For the few that aren't, we don't lose anything by compiling
them in the shared module global, but we also don't gain anything over
compiling them in the XPConnect compilation scope.

Going through the extension policy service rather than using
WebExtensionPolicy objects directly adds a lot of unnecessary overhead to
common operations on extension principals, and also makes the code more
complicated than it needs to be.

We also use weak references to policy objects here, since principals should
ideally lose as much of their elevated privileges as possible once the
extension instance that created them has been destroyed (which is something we
couldn't handle easily when we simply tracked ID strings).
