Attach more runtime info to `QuESTEnv`

[TysonRayJones]

Presently, QuESTEnv has fields:

typedef struct {

    bool isMultithreaded;
    bool isGpuAccelerated;
    bool isDistributed;

    bool isMpiUserOwned;
    bool isCuQuantumEnabled;
    bool isGpuSharingEnabled;

    int rank;
    int numNodes;

} QuESTEnv;

but some active PRs attach new fields, like isHipCompiled and isMpiGpuAware. We might as well attach all env info available in the QuEST backend to the QuESTEnv struct, so that users can query it programmatically (rather than just viewing the output of reportQuESTEnv().
