Remove frozen-abi-macro dependency on solana-logger

[steviez]

A couple items are logged, and we can simply use eprintln!() instead.

This is part of a larger initiative to remove solana-logger from the SDK as it seemingly belongs with Agave

[steviez]

Hmm ok, CI failed because of this line:

solana-sdk/frozen-abi-macro/src/lib.rs

Line 290 in 1ad7ca9

::solana_logger::setup();

Trying to figure out if we need this or not

Edit: I have updated the PR to remove the use of solana-logger from frozen-abi-macro

seems reasonable to print instead of log. logger should 100% be agave-logger not solana-logger

[steviez]

Hmm, I just noticed there are some log invocations in solana-frozen-abi like this one:

solana-sdk/frozen-abi/src/abi_digester.rs

Line 151 in 1ad7ca9

info!("updating with: {}", buf.trim_end());

These are basically unprintable now if we do not setup a logger; we could either setup env_logger where solana_logger::setup() was OR update all those to println!() too. Thoughts ?

I'd say go with println! everywhere there was an info!, and eprintln! everywhere there was a warn! or error!. These logs are just used for debugging frozen-abi changes

Just one comment on the nits bit

Looks great to me!
