[FL-3928] CLI rewrite

[portasynthinca3]

What's new

• Rewrote the CLI subsystem, which resulted in:
  • A nicer architecture
  • Reduced idle stack usage (4 KiB -> 0.75 KiB); reduced stack usage with a shell and a command running (4 KiB -> 3.75 KiB)
  • Support for commands stored in fal files as opposed to the flash
    • Reduced flash usage by ~20 KB
  • Better UX thanks to a real history and ANSI escape support in both directions (text formatting and keyboard shortcuts)
  • Semmingly better stability in companion apps even while using ANSI codes
  • About a 9% file transfer speed loss compared to the legacy implementation

Verification

• Test the CLI shell
• Test all the CLI commands
• Test all the tools that depend on the CLI (companion apps, fbt, production line tooling, etc.)
