chore: move attestation-provider-server crate from proxy repo

[steph-rs]

This PR moves attestation-provider-server crate from proxy repo.
As discussed in flashbots/attested-tls-proxy#156.

Changes:

• replaced attested-tls-proxy dependency with direct attestation path dependency
• fmt
• used tokio from workspace dependencies

Great! Thank you.

Will also get @0x416e746f6e to take a look.

For context, this moves the crate as-is over from the attested-tls-proxy repo, as it is more related to the contents of this repo than to the proxy.

thanks for this contribution.

small nit: can the provider server be made to fail with error if attestation type detection fails?

[0x416e746f6e]

suggestion:

Suggested change

	attestation = { path = "../attestation" }
	tokio.workspace = true
	attestation = { workspace = true }
	tokio = { workspace = true }
