chore: cherry-pick 7e0e52df283c from chromium

[ppontes]

[Blobs] Don't store BlobStorageLimits as a reference in transport strategy.

Rather than storing a const reference to something of unclear lifetime,
just make a copy. We could just copy the specific limits we need, but
there shouldn't be many TransportStrategy instances alive at the same
time anyway, so the cost of duplicating shouldn't be too high.
