svm repo split: decouple dev deps: reserved-account-keys

[buffalojoec]

Problem

We have to decouple any uses of agave- crates in the dev-dependencies of the crates slated to move to the new SVM repo.

Summary of Changes

Simply uses HashSet directly instead of bringing in the agave-reserved-account-keys dev-dependency only to use empty_key_set.

Part of #7317
