[NH5] Update build for nh5

[StephenOman]

Changes in this PR allow the C/C++ components to be built successfully (I hope).

Note: This PR contains a lot of changes so I'm happy to split it out to make it easier to review.

Changes:

1. Updated cmake build process to include Lua capabilities (largely based on cmake support for NetHack 3.7 NetHack/NetHack#662)
2. Remove obsolete lev_comp and dgn_comp targets
3. Refactor rl_procs window interface to match updated NetHack 5 specification
4. Update Python bindings including change to support the gendered names for monsters
5. Scope & other minor changes for RNG functions to match new function locations
6. Refactor NLE function declarations to match NH5 style (removal of macros such as NDECL, FDECL etc.)
