feat: reduce scope of crypto module

[SgtPooki]

Discussed during https://pl-strflt.notion.site/js-libp2p-get-rid-of-node-forge-331d2e274b5e46e6be3f697dcf7b2c4d?pvs=4

create a new /packages/crypto folder where all the stuff that we don't use internally in libp2p

• There are a lot of RSA keys on the network (e.g. peerId string "Qm...")
• We can't remove import/export of the keys yet (i.e. go from pkcs1 to jwk, or pkix to jwk)
• internal format is pwk,
• external pkix for public keys and pkcs1 for private
• we should move some stuff out that we can, which reduces effort later

Tasks

Beta Give feedback

1. remove the encryption stuff?
2. replace node-forge with noble's pbkdf2 implementation (there is a PR open for this already, not added because we haven't got rid of node-forge yet)
