Fix gesture completion

[MatkovIvan]

Proposed Changes

• Send Release only to pressOwner
• Send Release even if it's under focused to finish gestures for pressOwner
• Update hovered state (send Exit) if owner appears under focused

Testing

Test: run PopupTest or demo app

Issues Fixed

Fixes:

• Improve handling multi-owner input compose-multiplatform#3349
• COMPOSE-175

• Move mouse into a menu item in the context menu
• Release mouse button to select menu item
