Activate the default console when user interaction is required for
the processing of TPM 2 physical presence interface opcodes.
Background:
TPM 2 physical presence interface (PPI) opcodes need to be handled before
the TPM 2 platform hierarchy is disabled. Due to this requirement we will
move the function call to handle the PPI opcodes into
PlatformBootManagerBeforeConsole() which runs before the initialization
of the consoles. However, since for interaction with the user we need
the console to be available, activate it now before displaying any message
to the user.
