v1.17: Combine builtin and BPF compute cost in cost model (backport of #29)

[mergify]

Problem

feature gate solana-labs#30620 has been activated everywhere, SVM now consumes compute units uniformly for both builtins and BPF instructions. Cost Model should no longer estimate their cost separately.

Original PR: solana-labs#32080

Summary of Changes

• combine builtin and bpf cost into programs_execution_cost, update metrics reporting as well.
• update tests

lgtm - should fix double counting of builtins and free up some blockspace

We never got folks on board to BP this to v1.17 but moot point as v1.17 is now EOL with MNB on v1.18 - closing this out
