ARKODE Order Checking Improvements

[Steven-Roberts]

Replaces a few thousand lines of hard-coded order conditions with systematic, arbitrary order checking.

In draft status because I'd like to see about changing the return values of ARKodeButcherTable_CheckOrder and ARKodeButcherTable_CheckARKOrder. Currently, they handle return values of -1 and -2 inconsistently. I'd like to propose returning ARK_* errors, e.g.,

• ARK_SUCCESS, ARK_MEM_NULL, ARK_MEM_FAIL, etc
• A new ARK_ORDER_OVERESTIMATE error code if supplied order is greater than computed
• ARK_WARNING or new ARK_WARNING_ORDER_UNDERESTIMATE if supplied order is less than computed

I suppose that would be considered a breaking change, though.
