Introduce a new `query_with_param_types` method that allows to specify Postgres type parameters. This obviated the need to use prepared statementsjust to obtain parameter types for a query. It then combines parse, bind, and execute in a single packet.

Fix cancellation of TransactionBuilder::start

If a query returns no data, we receive `Message::NoData`, which signals
the completion of the query. However, we treated it as a no-op, leading
to processing other messages and eventual failure.

This PR fixes the issue and updates the `query_typed` tests to cover
this scenario.

For `query_typed`, deal with the no-data case.

The impl now directly computes `Timestamp` rather than going through
`DateTime` and `Zoned`.

`Timestamp` already has impl and is semantically accurate for mapping to `timestamptz`, unlike `Zoned`.
End users can do their own conversions from `Timestamp` to `Zoned` if desired.

Support AIX keepalive

This sets the smallest unit to microseconds when calculating time deltas.

Previously, the number of microseconds was expressed improperly because
the rounding was not set.

This adds tests in the same fashion as the existing ones for `chrono`
and `time`.

Overflow is now handled using fallible operations.
For example, `Span:microseconds` is replaced with `Span::try_microseconds`.
Postgres infinity values are workiing as expected.

All tests are passing.

The implementation was previously removed as per jiff author comment.

`test_date_time_params` and `test_with_special_date_time_params` could fail when run with a non-UTC system time zone.

In Postgres, if no time zone is stated in the input string, then it is assumed to be in system time.
This means that in these tests, a correctly parsed `DateTime<Utc>` could be compared to an incorrectly offset time.

The offset component is now included in the test strings of these tests. This component is already present in the test strings for `time::OffsetDateTime`.

Fix `chrono::DateTime<Utc>` tests

Add Jiff support

This patch is based on tag readyset-20240301.  Previously, we
maintained this repo as a fork and merged with upstream occasionally.
Now we sync to upstream, discard some now unnecessary changes, and
dump all of our custom changes into a single commit so it may be
more easily rebased for as long as this fork may live.
