svm repo split: fork measure

[buffalojoec]

The solana-measure crate is a simple utility lib that's used across the validator to measure duration. It's not specific to any one component or domain of Agave, so it doesn't really make sense to live in SVM and have Agave import it.

Instead, since the crate is so simple and has no dependencies, it's actually easier to just fork it and maintain a separate version of solana-measure in the new SVM repo (solana-svm-measure).

Part of #7317

[mergify]

The Firedancer team maintains a line-for-line reimplementation of the
native programs, and until native programs are moved to BPF, those
implementations must exactly match their Agave counterparts.
If this PR represents a change to a native program implementation (not
tests), please include a reviewer from the Firedancer team. And please
keep refactors to a minimum.
