Allow disabling STB_*_IMPLEMENTATION (#578)

When having stb_rect_pack or stb_truetype used elsewhere in your project, Nuklear could cause conflicts. This change adds `NK_NO_STB_RECT_PACK_IMPLEMENTATION` or `NK_NO_STB_TRUETYPE_IMPLEMENTATION` to allow disabling adding `STB_RECT_PACK_IMPLEMENTATION` or `STB_TRUETYPE_IMPLEMENTATION`.
