[AMDGPU] Convert PrologEpilogSGPRSpills from DenseMap to sorted vector (#90957) In practice PrologEpilogSGPRSpills never has more than 3 entries so DenseMap is overkill. In addition this means that iteration happens in register number order, instead of DenseMap's hashed order, so it will not be affected by future patches that define new physical registers. This should reduce future test case churn.
