tools: function names for the Ghidra project, Hold-Key test helper

- tools/names.txt lists identified sacred.exe functions ("0xADDR
  Class::Method"); rename.ps1 / Rename.java apply them to the persistent
  Ghidra project, so decompiles read with real names.
- decompile.ps1: parameters other than the addresses are named-only (the
  first address was taken as -Out).
- game-input.ps1: Hold-Key for polled keys such as movement.
