Start refactoring to reduce executable type knowledge.

This creates executable detection functions, a globally shared enum for
describing an executable type, and reduces the number of classes and
locations with executable specific knowledge.

These changes, along with moving architecture specific classes into their
own files should make it easier to produce special purpose clients that
only contain the code required to apply their own form of patch.

DisassemblerWin32EXE, ImagePE, CourgetteWin32X86PatchGenerator, and
CourgetteWin32X86Patcher, and ensemble handling are all heavily affected here.

This should have no effect on the behavior of the system yet, and is instead
all prep-work.

This is the same as an earlier CL, except that ParseHeader will now return
an error for 64 bit PE executables, and resource only DLLs. This is because
the detection factories depend on ParseHeader to decide if a given file
is supported.

BUG=None
TEST=Unittests
