Apply GCC's tainted_args attribute to library entrypoints

The implementation applies `__attribute__((tainted_args))` by
integrating it into the existing ABI macro annotations.

In the process, quite a number of APIs were discovered to be unsafe in
ways that were not immediately fixable. Often this is because they lack
arguments that enable the appropriate bounds-checking to be applied.

Redesigning them is work beyond the scope of the immediate
effort. Instead, we also introduce a new annotation,
LIBPLDM_ABI_DEPRECATED_UNSAFE, that simply lacks
`__attribute__((tainted_args))` and therefore doesn't trigger the extra
analysis.
