35284: storage,kv: make transaction deadline exceeded errors retriable r=andreimatei a=andreimatei

Before this patch, they were opaque TransactionStatusErrors.
The belief is that we should only be seeing such errors when a
transaction is pushed by minutes. Shockingly, this seems to hapen enough
in our tests, for example as described here: #18684 (comment)

This patch marks the error as retriable, since it technically is.

This patch also changes the semantics of the
EndTransactionRequest.Deadline field to make it exclusive so that it
matches the nature of SQL leases. No migration needed.

Touches #18684

Release note (sql change): "transaction deadline exceeded" errors are
now returned to the client with a retriable code.

This PR addresses a test flake introduced by enabling follower reads in
conjunction with #35130 which makes follower reads more generally possible
in the face of lease transfer.

Fixes #35758.
