Original commit message:
[ptr-compr] Fix multi-cage mode
This CL introduces PtrComprCageAccessScope which sets/restores current
thread's pointer compression cage base values. It's supposed to be used
by V8 jobs accessing V8 heap outside of v8::Isolate::Scope or
i::LocalHeap or i::LocalIsolate scopes (they already ensure that the
cage base values are properly initialized).
For all other build modes PtrComprCageAccessScope is a no-op.
For simplicity reasons the multi-cage mode is made incompatible with
external code space.
Bug: v8:13788, v8:14292
