/**
This function provides a platform-specific method to detect whether the platform
is operating by a physically present user.
Programmatic changing of platform security policy (such as disable Secure Boot,
or switch between Standard/Custom Secure Boot mode) MUST NOT be possible during
Boot Services or after exiting EFI Boot Services. Only a physically present user
is allowed to perform these operations.
NOTE THAT: This function cannot depend on any EFI Variable Service since they are
not available when this function is called in AuthenticateVariable driver.
@retval TRUE The platform is operated by a physically present user.
@retval FALSE The platform is NOT operated by a physically present user.
