removes dynamic cast and dynamic dispatch from connection-cache (#30128)
Dynamic dispatch forces heap allocation and adds extra overhead.
Dynamic casting as in the ones below, lacks compile-time type safety:
https://github.com/solana-labs/solana/blob/eeb622c4e/quic-client/src/lib.rs#L172-L175
https://github.com/solana-labs/solana/blob/eeb622c4e/udp-client/src/lib.rs#L52-L55

The commit removes all instances of Any, Box<dyn ...>, and Arc<dyn ...>,
and instead uses generic and associated types.

There are only two protocols QUIC and UDP; and the code which has to
work with both protocols can use a trivial thin enum wrapper.

With respect to connection-cache specifically:
* connection-cache/ConnectionCache is a single protocol cache which
  allows to use either QUIC or UDP without any build dependency on the
  other protocol.
* client/ConnectionCache is an enum wrapper around both protocols and
  can be used in the code which has to work with both QUIC and UDP.
