The motivation for this PR is described in #5512.

Relevant issues

Closes #5512

Changes

API changes

Behavioural changes

• The following things are now controllable by permissions:
  • Chatting
  • Emoting
  • Placing, breaking and interacting with blocks
  • Dropping, picking up, and activating items
  • Creating new items (e.g. from the creative inventory)
  • Attacking and interacting with entities
  • Flight
  • CanPlaceOn and CanDestroy checks
  • Creative-style instabreak & destruction of indestructible blocks
• Game modes now apply abilities by setting a permission group to true on the player.
• Various places that previously used game mode checks (e.g. dropping items, interacting with blocks, attacking entities) now check for permissions instead.

Backwards compatibility

Should be fully backwards compatible.

Follow-up

Add further permissions for the following:

• Opening containers
• Remove some deprecated setters that have been migrated to permissions

Tests

This has been tested in-game.

Blocking items:

• New permissions need descriptions localizing
• Behavioural BC break of setAllowFlight() - this can be addressed by removing the base permission during gamemode change - since we'll probably remove setAllowFlight() in major-next, this workaround is probably OK
