XPConnect calls this method during shutdown after the pointer to the
singleton nsScriptSecurityManager has been cleared, so it is actually
calling it with a null |this|. Nobody noticed this because it isn't
actually using |this|. This patch turns it into a static method to
make the sanitizers happy.

Lots of these callbacks have a non-`void*` final parameter, which UBSAN
complains about. This commit changes them to have a `void*` parameter.
This requires undoing the machinery added in the first two commits of bug
1473631: `TypePrefChangeFunc` and `PREF_CHANGE_METHOD`. The resulting code is
simpler (which is good) and more boilerplate-y (which is bad) but avoids the
undefined behaviour (which is good).

This patch adds support for including content_scripts CSP in the extensions
manifest, along with all interfaces necessary to access the CSP value. This does not
implement actual use of the CSP for content scripts.

In this patch, we add the propagation of the first party domain through
the tabContext while creating OOP browsers. In the window.open() case,
we will propagate the first party domain from the opener's browser parent.
And in the frame case, we will propagate it from the manager of the
browserBridgeParent of the OOP frame.

`CreateSuffix` is irreversible by `PopulateFromSuffix` because it uses a multi-to-one mapping.
Since only ':' will happen in a IPv6 format, we can make it a 1-to-1 mapping so that the `firstPartyDomain` is consistent after `CreateSuffix` and `PopulateFromSuffix`.

This patch does several things. Because Workers aren't on the main thread,
many of the things done are in the name of off main thread access.
1) Changes a parameter in IsEvalAllowed from a nsIPrincipal to a bool.
We only used the principal to determined if it was the System Principal.
Principals aren't thread safe and can only be accessed on Main Thread, so
if we passed a Principal in, we would be in error. Instead only pass in
the bool which - for workers - comes from a thread-safe location.
2) Separates out the Telemetry Event Recording and sending a message to the
console into a new function nsContentSecurityUtils::NotifyEvalUsage. (And
creates a runnable that calls it.)
We do this because we will need to only call this method on the main thread.
Telemetry Event Recording has only ever been called on the Main Thread.
While I possibly-successfully cut it over to happen Off Main Thread (OMT)
by porting preferences to StaticPrefs, I don't know if there were other
threading assumptions in the Telemetry Code. So it would be much safer to
just continue recording Event Telemetry on the main thread.
Sending a message to the console requires calling GetStringBundleService()
which requires main thread. I didn't investigate if this could be made
thread-safe, I just threw it onto the main thread too.
If, in IsEvalAllowed, we are on the main thread - we call NotifyEvalUsage
directly. If we are not, we create a runnable which will then call
NotifyEvalUsage for us on the main thread.
3) Ports allow_eval_with_system_principal and allow_eval_in_parent_process
from bools to RelaxedAtomicBool - because we now check these prefs OMT.
4) In RuntimeService.cpp, adds the call to IsEvalAllowed.
5) Add resource://gre/modules/workers/require.js to the allowlist of eval
usage. This was the script that identified this gap in the first place.
It uses eval (twice) for structural reasons (scope and line number
massaging.) The contents of the eval are the result of a request to a
uri (which may be internal, like resource://). The whole point of this
is to implement a CommonJS require() api.
This usage of eval is safe because the only way an attacker can inject
into it is by either controlling the response of the uri request or
controlling (or appending to) the argument. If they can do that, they
are able to inject script into Firefox even if we cut this usage of eval
over to some other type of safe(r) script loader.
Bug 1584564 tracks making sure calls to require.js are safe.
6) Adds cld-worker.js to the allowlist. Bug 1584605 is for refactoring that
eval usage, which is decidedly non-trivial.
7) Does _not_ enforce the eval restrictions for workers. While I've gotten
try to be green and not throw up any instances of eval-usage by workers,
it is much safer to deploy this is Telemetry-only mode for Workers for
a little bit to see if anything pops up from the Nightly population.
Bug 1584602 is for enforcing the checks.

Finally, here we add the virtual method isSystemOrAddonPrincipal to the
JSPrincipal object.
We also add it to nsJSPrincipal (where it has an easy implementation), and
to carry classes that are used by JS tests and the shell.
