ruby: slicc: Dynamically find+declare all MachineTypes

To avoid statically declaring MachineTypes that can be used by Ruby protocols,
modify the SLICC parser to dynamically collect the different machine types
from all the available protocols to declare them in the MachineTypes generated
enum. This change declares the full set of types, but only generates the
controller files for the specified protocol.

Built MI_example and MOESI_hammer in gem5. Also applied a personal patch

that adds MachineType-dependent code to RubyMemoryController, and

successfully built a protocol that does not define machines required by

that that code. Benchmarks run in each build, and MachineType-specific

functionality appears correct.
