Bump minimum Solana crate versions to 1.17.3

[acheroncrypto]

Problem

The latest version (0.30.0) is using ProgramError::ArithmeticOverflow which was added in solana-labs/solana#33767 and does not exist before solana-program 1.17.3. However, we still support 1.16 in our version requirements:

anchor/lang/Cargo.toml

Line 60 in 518b73f

solana-program = "1.16"

We could potentially fix this by introducing a new error variant ourselves or using an existing error variant, but given we're going to need to bump our Solana version anyway, and the fact that 1.17.3 release was published ~8 months ago, it's better to just bump the versions.

Summary of changes

Bump the minimum version of all Solana crates to 1.17.3.

Closes #2949
