Add a brief explanation of the data section layout for the unwind data that the
Windows on ARM EH models. This is simply to provide a rough idea of the layout
of the code involved in the decoding of the unwinding. Details on the involved
data structures are available in the associated support header. The bulk of it
is related to printing out the byte-code to help validate generation of WoA EH.
No functional change.

Add support to llvm-readobj to decode Windows ARM Exception Handling data. This
uses the previously added datastructures to decode the information into a format
that can be used by tests. This is a necessary step to add support for emitting
Windows on ARM exception handling information.
A fair amount of formatting inspiration is drawn from the Win64 EH printer as
well as the ARM EHABI printer. This allows for a reasonably thorough look into
the encoded data.
