make integer/floating point types configurable through cmake

[superwhiskers]

overview

some workflows may benefit from wider integer or floating point types. these should be configurable through options passed to cmake, which should correctly force-disable things currently incompatible with certain types (such as some of the hip and probably cuda code). additionally, they should set the corresponding type aliases (real_type/index_type) in resolve/Common.hpp and resolve/lusol/lusol_precision.f90

additional notes

• the hip/cuda code could be modified to be compatible with wider integer types (in the event native support is not possible) by partitioning the job, probably
• an instance in which another similar project has done this sort of thing can be found here¹
