Keyhan Vakil 00dab30fd2 deps: V8: cherry-pick 475c8cdf9a95 
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

V8 debug helper

This library is for debugging V8 itself, not debugging JavaScript running within V8. It is designed to be called from a debugger extension running within a native debugger such as WinDbg or LLDB. It can be used on live processes or crash dumps, and cannot assume that all memory is available in a dump.
