deps: revert 9136dd8088a9 from upstream V8

Reverting this enables us to provide slower, but longer-lasting
replacements for the deprecated APIs.

Original commit message:

    Put back deleted V8_DEPRECATE_SOON methods

    This partially reverts
    https://chromium-review.googlesource.com/c/v8/v8/+/1177861,
    which deleted many V8_DEPRECATE_SOON methods rather than moving them to
    V8_DEPRECATED first. This puts them back and marks them V8_DEPRECATED.

    Note V8_DEPRECATED that were deleted in the same CL stay deleted.

    NOTRY=true
    NOPRESUBMIT=true
    NOTREECHECKS=true
