Add support for SPL Token Types

[julianzamt]

Is your enhancement request related to a problem? Please describe.
Trying to build a simple defi, I needed to perform checks on Mint and Token types. This includes both data and metadata checks

Describe the solution you'd like
To add support for these types with the built-in metadata checks + data constraints supported by Anchor, both in Anchor and Solana Native.

Describe alternatives you've considered
I manually placed checks inside my stubs.

Additional context
Metadata is referred to account len, account program owner, pda address, discriminator, mint address (maybe others?)
Data constraints is referred to token account authority, token account mint, mint authority (maybe others?)
