ee0d204bf6 Wrap JSAutoRequest and replace usage of JSContext* with the wrapper.
JSAutoRequest is required before calling into most JSAPI methods, for GC
reasons.
Calling it is required and fragile as one must not forget.
Further, SM52 and later make manipulating JSContext* dangerous as that
can cross Compartment(Realm in SM68) barriers (and ScriptInterface now
matches a Compartment).

The solution to both problems is to avoid using JSContext* in 0 A.D.
itself. To achieve this, a Request class is introduced, and must be used
to access a JSContext* from a scriptInterface. Further, Request is
passed to other ScriptInterface functions isntead of JSContext*, making
it obvious that the caller has already called it, reducing errors and
redundant JSAutoRequest calls.
Only JSNative functions now get a naked JSContext* without protection,
but the likelihood of forgetting a request is lower since many
ScriptInterface functions now expect it.

JSContext* is directly passed to JSAPI functions only.

Part of the SM52 migration, stage: SM45 compatible

a84e2e57df Use ScriptInterface::CreateObject for ToJSVal<CColor>, and for ToJSVal<Grid<u8> >, ToJSVal<Grid<u16> > used by the AIManager obtaining the pathfinder grid.
Make that function static, so that it can be used for these functions
without slowly having to obtain the ScriptInterface instance using
GetScriptInterfaceAndCBData just to get the JSContext again.
Remove few redundant conversions for CreateObject arguments.

7ecd1d2c34 Clean some forward declarations.
Remove unused (wrong copy&paste) includes from 86fcf0de8c in
JSInterface_ModIo.*, initially hinted at by leper.
Remove a forward declaration in JSInterface_Console.h that should have
become an include with 4b1297b328, because CxPrivate must be declared
before its reference too.
Remove a forward declaration in JSInterface_Mod.h from 64bfa089af that
should have been the include added in af03c72f76 which in turn omitted
to remove this forward declaration.
Remove a forward declaration in Renderer.h that became unused with
1ddd24bb8c.
