Add a "combination" assert scope class, which combines multiple existing assert scopes. This will allow scopes with functional overlap, e.g. DisallowGarbageCollection and DisallowHeapAllocation, to share an assert type rather than rather than requiring users to remember to set both. To demonstrate this, this redefines DisallowGarbageCollection to a combination of DisallowHeapAllocation and a new DisallowSafepoints, and some of the DCHECKs checking both are simplified to only check one or the other, as appropriate. The combination classes become subclasses of the existing assert scopes, so that they can be used in their place as e.g. a function parameter, e.g. DisallowGarbageCollection can be passed to a function expecting const DisallowHeapAllocation&. As a drive-by, this also changes the per-thread assert scopes to use a bitmask, rather than a bool array, to store their per-thread data. The per-isolate scopes already used a bitmask, so this unifies the behaviour between the two.
