Previously, the base math headers included GMP headers in all cases. This was problematic because we don't want all modules that use the math headers to depend on GMP, and the unnecessary includes could theoretically have detrimental effects to compile times. Now `BLI_math_mpq.hh` depends on `BLI_math_base.hh`, so if a file needs to use exact arithmatic, it can just include the former. Differential Revision: https://developer.blender.org/D15079
