Add error message when Mint and TokenAccount with init are not ordered correctly

[CanardMandarin]

Hi,

Following the closed PR #2467, here is another proposal for the issue #2463.
Now, the following code will throw an error.

#[derive(Accounts)]
pub struct TestInitConstraint<'info> {
    #[account(
        init,
        payer = payer,
        token::mint = mint,
        token::authority = payer,
    )]
    pub token: Account<'info, TokenAccount>,

    #[account(
        init,
        payer = payer,
        mint::decimals = 0,
        mint::authority = payer,
    )]
    pub mint: Account<'info, Mint>,

    #[account(mut)]
    pub payer: Signer<'info>,
    pub system_program: Program<'info, System>,
    pub token_program: Program<'info, Token>,
}

What do you think?

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

A member of the Team first needs to authorize it.

Thank you, I think this is a much better solution.
