deps: cherry-pick fc0ddf5 from upstream V8

Original commit message:

    [snapshot] Always align embedded blob code pointer and size

    Other platforms besides ARM64 Windows may also have alignment
    requirements, e.g. PPC and s390. These requirements may affect
    both the code pointer field and the size field, and so they
    each need alignment directives because they are stored in
    different sections.

    Since aligning wastes a handful of bytes at most, not making
    alignment conditional on the platform type seems like a good idea.
