OvmfPkg/TPM PPI: Connect default consoles for user interaction
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.
