OcBootManagementLib: Disable builtin picker timeout on unbootable selection from Apple picker; change from INFO to WARN if cannot start requested Apple picker

This fixes regression introduced by https://github.com/acidanthera/OpenCorePkg/commit/f604848c61d7082860fceb23ac54d5e03e620478.

 - Remove long-standing unused ConsoleControlInstall method
 - Minor codestyle fix
 - Improve doc wording

The renderer already (esp. since recent changes incl. reset to controlled on cls)
manages its own transitions to controlled, so we just need to indicate uncontrolled
in cases where something else has been rendering graphics

 - Perform full clear screen on switch from graphics to text mode,
   if marked uncontrolled
 - Suppress remaining console coloured output (screen clear and
   cursor, text was already handled) if in graphics mode
 - Remain uncontrolled while in graphics mode
 - Improve builtin renderer screen size calculations
   o Although we appear to lose a small amount of height (i.e. up
     to one row) with the new font size scaled vertical padding,
     we were actually losing it anyway with the previous screen
     size calculation
 - Re-order initialisation of builtin mode
   o Avoid producing uncontrolled text with old text protocol,
     after resync screen clear of new controlled protocol

 - Avoid additional clear screen when resyncing
 - Use same values to trigger full clear screen after background
   colour change as after mark uncontrolled
 - Only scroll used width when controlled
 - Reset controlled area after clear screen
 - Fix mConsoleMaxPosY init error for controlled mode
   o Present since 76e889f8
 - Fix ConsoleControl wording in docs
 - Add ASSERTS and comments

 - Reverts part of commit 2439d584.
 - Reverts commit a189bd53.
 - Reverts part of commit b07843fe.
