4903: Implement generic_hash() host function to support hashing algorithms r=igor-casper a=igor-casper

This PR directly addresses #4892, referencing #4411 as prior work.

Adds host function called generic_hash(input, type) with support for the following types:
- HashAlgorithm::Blake2b - using the existing blake2b implementation,
- HashAlgorithm::Blake3 - introducing the blake3 library,
- HashAlgorithm::Sha256 - introducing the sha2 library,

**Example usage**
```rs
#![no_std]
#![no_main]

extern crate alloc;
use alloc::string::String;

use casper_contract::contract_api::cryptography;
use casper_types::crypto::HashAlgorithm;

#[no_mangle]
pub extern "C" fn call() {
    let data = "sha256 hash test";
    let expected = [0x29, 0xD2, 0xC7, 0x7B, 0x39, 0x7F, 0xF6, 0x9E, 0x25, 0x0D, 0x81, 0xA3, 0xBA, 0xBB, 0x32, 0xDE, 0xFF, 0x3C, 0x2D, 0x06, 0xC9, 0x8E, 0x5E, 0x73, 0x60, 0x54, 0x3C, 0xE4, 0x91, 0xAC, 0x81, 0xCA];

    let hash = cryptography::generic_hash(data, HashAlgorithm::Sha256);
    
    assert_eq!(
        hash, expected,
        "Hash mismatch"
    );
}
```

**Notes**
- Blake2 is implemented in the types crate and it's been that way for some time, ideally it would be moved into the cryptography module where blake3 and sha256 reside
- The costs were referenced from #4411
