deps: V8: cherry-pick 87ce4f5d98a5

Original commit message:

    [ic] use CSA_DCHECK in CodeStubAssembler::SharedValueBarrier

    Since the code is generated unconditionally, using a DCHECK to check
    that shared RO heap is enabled breaks builds with
    v8_enable_shared_ro_heap set to false, this patch turns that into a
    CSA_DCHECK so it only crashes when V8 actually attempts to store into
    a shared struct while the RO heap isn't shared at run time.
