License split: MIT top-level, zlib for gamecube/.

Top-level LICENSE.md is now MIT, applying to repo-wide scaffolding (CI
workflows, build infra, top-level README). Each console subdirectory
carries its own LICENSE.md matching its upstream origin —
gamecube/LICENSE.md is the original zlib license preserving corenting's
notice for code derived from GC-Controller-Test.
