Add header guards to files that were missing guards. Remove #endif comments
as they don't seem common in LLVM (we can easily add them back if we decide
they're useful)
Changes made by clang-tidy with minor tweaks.

Replicate the fact that ARM::WinEH::RuntimeFunction purposefully does not merge
functions to accommodate raw data access use cases in tools such as readobj.
Pointed out by Renato during post-commit review.
No functional change.

Introduce the support structures necessary to deal with the Windows ARM EH data.
These definitions are extremely aggressive about assertions to aid future use
for generation of the entries and subsequent decoding.
The names for the various fields are meant to reflect the names used by the
Visual Studio toolchain to aid communication.
Due to the complexity in reading a few of the values, there are a couple of
additional utility functions to decode the information.
In general, there are two ways to encode the unwinding information:
- packed, which places the data inline into the
_IMAGE_ARM_RUNTIME_FUNCTION_ENTRY structure.
- unpacked, which places the data into auxiliary structures placed into the
.xdata section.
The set of structures allow reading of data in either encoding, with the minor
caveat that epilogue scopes need to be decoded manually by constructing the
structure from the data returned by the RuntimeFunction structure.
These definitions are meant for read-only access at the current point as the
first use of them will be to decode the exception information.
