Just noting that the values returned from these (partially imaginary) APIs would be hard to use correctly. The two resources might be inter-dependent. E.g. intel can have four hardware breakpoints OR four hardware watchpoints. However, it cannot have four HW breakpoints AND four HW watchpoints. And it might not be able to set even all four as the (linux) kernel might be using some of the registers for its own purposes (something to do with perf, I believe).
