feat: add anchor bindings anchor-lang

[mgild]

This change adds wrapper bindings for the AddressLookupTable program and AddressLookupTable Account.

Usage:

#[derive(Accounts)]
pub struct Action<'info> {
    pub lut_program: Program<'info, AddressLookupTable>,
    pub lut_signer: Signer<'info>,
    pub lookup_table: Account<'info, AddressLookupTableAccount<'info>>,
}

Tests:

cd lang
cargo build

@mgild is attempting to deploy a commit to the coral-xyz Team on Vercel.

A member of the Team first needs to authorize it.

This has been requested before, so thank you for adding this!

It would be very helpful to have some tests for these types. They don't need to be very complicated; just some tests to check compilation and basic functionality. Compilation tests are especially important given how easy it is to miss the idl-build feature impl.

There are also a couple more issues that I mentioned in the comments, but it looks good otherwise.
