Split the Interrupt Controller Structure length validation in the
acpiview UEFI shell tool into two logical parts:
1. Ensuring MADT table parser forward progress.
2. Preventing MADT table buffer overruns.
Also, make the condition for infinite loop detection applicable to
all types of Interrupt Controller Structures (for all interrupt models
which can be represented in MADT). Check if the controller length
specified is shorter than the byte size of the first two fields
('Type' and 'Length') present in every valid Interrupt Controller
Structure.
