This adds the flag itself and a means of setting it for a cycle collected class.
The proper way to do this would be to add versions of all the NS_DECL_CYCLE_COLLECTION_CLASS macros that also set this flag but we end up needing to create separate versions for five of these and it's a lot of macro code to add. Here I added a version of NS_IMPL_CYCLE_COLLECTION_CLASS that sets the flag. This has the disadvantage that it wouldn't work well if we needed to set the flag on a base class as we'd have to use this macro for every derived class. However that situation doesn't actually arise (and ideally this flag will bet set on the fewest number of classes possible).

Currently classes derived from nsCycleCollectionParicipant have one flag to pass and adding more makes the class delcaration macros get messy really quickly. This patch replaces boolean flags with a bitfield which makes adding new flags easier.

This method turned out to only be used for tracing wrapper cached things. The wrapper cache has its own way of implementing barriers and contains a raw JSObject pointer. Changing this trace method to take an nsWrapperCache pointer (effectively a JSObjct**) enforces correct use of Heap<T> for other TraceCallbacks callers.

clang-tidy is complaining about an extra else in
NS_INTERFACE_MAP_ENTRIES_CYCLE_COLLECTION. Not hurting anything, but
could be cleaned up anyways.

Add macro for nsISupports inheriting classes that need cycle
collection and only inherit from one parent, with no interface table
needed. Takes care of map and addref/release calls.

QIing to CC interfaces shows up in Speedometer profiles for a few
classes. Presumably there are many of these objects being created and
destroyed. By making these classes check first for the CC interfaces
directly, rather than going up the inheritance chain, this overhead
should be reduced.

The main purpose of defining this is to make conversion of places that
use the non-CC variant easier. There are many more places that could
be converted to use these new macros, if somebody felt motivated.

Replace it with NS_INTERFACE_MAP_BEGIN_CYCLE_COLLECTION, because it
has been the same for a while.

At the same time, remove the MOZ_STATIC_ASSERT_VALID_ARG_COUNT, which
doesn't actually work for more than 50 arguments(*), and which is now not
useful to detect 0 arguments.
(*) the build fails, but not directly thanks to the static_assert it
expands to.

This way we can't end up with a situation in which an ancestor doesn't care about skippability but a descendant does and doesn't get it, because the ancestor just claimed no skippability was needed.
