security: Use VDL's mechanism for wire <-> native conversions for
Blessings.

This commit is the counterpart to the API change in:
https://vanadium-review.googlesource.com/6290

Mostly simplifies, but there are some rough edges still left
which will be addressed in separate commits:
(1) At a few places, the caller wants to access the underlying
    certificate chains of a security.Blessings object.
    Have to work out this API, but for now they either use
    security.MarshalBlessings or do a VOM-roundtrip (when
    performance is a non-concern)
(2) The BlessingStore implementation can be simplified considerably
    now, and should have a clear wire spec (.vdl file).
(3) The persistent store used by the mgmt code
    (veyron/services/mgmt/lib/fs) is using GOB to write out
    serialized forms. There is a plan to convert this to VOM
    but in the mean time I had to do something ugly - translate
    from application.Envelope (which is no longer GOBable) to
    a different type. This will go away once the store is converted
    to VOM.
