Subject: [PATCH 1/2] rent-collector: Deprecate the crate (#262)

#### Problem

As noted in #226, the rent collector crate and struct are no longer
needed, and with https://github.com/anza-xyz/agave/pull/7297, will no
longer be used.

#### Summary of changes

Mark the crate as deprecated, so that we can backport and release the
change, then delete the crate entirely.

(cherry picked from commit 0cabe5d3c8bfbfd875a08663392cbb9238b87140)
