Add Shank IDL to Program ELF

[ngundotra]

Add the compressed IDL to the program's binary under a section header called .solana.idl.

Adding include_idl!() increases program size by 4K bytes.

• Before including compressed IDL, asset program size: 244K
• After including .solana.idl, asset program size: 248K

@ngundotra This is super cool!

I think we need to install node + pnpm on the lint_rust step for CI to work. Probably all we need is this block:

- name: Install Node.js
  uses: nifty-oss/actions/install-node-with-pnpm@v1
  with:
     version: ${{ env.NODE_VERSION }}
     cache: ${{ env.CACHE }}
     dependencies: true

on the lint_rust step on main.yml after installing Rust.

@febo I could use some help fixing the rust client tests :) when you have a moment

Having a look now.

@ngundotra We need to add the node + pnpm install action to both build and test workflows:

- name: Install Node.js
  uses: nifty-oss/actions/install-node-with-pnpm@v1
  with:
     version: ${{ env.NODE_VERSION }}
     cache: ${{ env.CACHE }}
     dependencies: true

Similarly to what was done for lint.
