avm: Remove once_cell dependency

[acheroncrypto]

Problem

Rust's standard library supports the functionality of once_cell::sync::Lazy with std::sync::LazyLock since Rust v1.80 (stable).

We can switch to using the std implementation to remove the once_cell dependency from avm:

anchor/avm/src/lib.rs

Line 15 in 4b12678

pub static AVM_HOME: Lazy<PathBuf> = Lazy::new(|| {

anchor/avm/Cargo.toml

Line 22 in 4b12678

once_cell = "1.8.0"

Summary of changes

Remove the once_cell dependency from avm.

avm has nothing to do with which Solana version you use.
