Support run on player build [experimental]

[nowsprinting]

Overview

Added support for running player builds.
It is needed for performance testing, aging, etc.

It's still unfriendly and time-consuming.
So, I've made it an experimental feature.

Please see the README for the differences in specifications.

Main changes

• Fix to Launcher to run on the player build
  • Fix tests run on player
  • Refactor around launch/terminate
• Fix file output path on the player
• Add command line argument for launch autopilot on player

Chores, fix bugs

• Fix survive agents after terminate
• Fix reset trigger on OneTimeAgent
• Fix InitializeOnLaunchAutopilotAttribute inherit PreserveAttribute
• Fix tests
• Fix READMEs
• Remove not used asset files

Priority

I'd want it to be released within 1 to 2 weeks.
