feat: remove Math library source, header, tests, and build references from MSVC projects

Remove the entire wren_math.c and wren_math.h implementation files, delete all math test scripts under test/math/, and strip the WREN_USE_LIB_MATH compile flag from wren_common.h. Also remove the wrenLoadMathLibrary call from wren_vm.c and delete the wren_math.c/h entries from both the MSVC project file and its filters file.
