dsp: firmware_update: Iterators for downstream device descriptors

Provide an ergonomic and safe means to iterate through downstream
devices and their descriptors while avoiding the need to allocate. The
strategy leaves the library user to make their own choices about how the
data is handled.

The user-facing portion of the change takes the form of two new macros,
to be nested inside one another:

```
foreach_pldm_downstream_device(...) {
foreach_pldm_downstream_device_descriptor(...) {
// Do something with the device-specific descriptor
}
}
```

Examples uses are provided in the documentation and in changes to the

```

Ultimately the check was trying to satisfy the following from GCC's
analyzer:

```
| 1345 | size_t l_num_entities = entity_association_pdr->num_children + 1;
| | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
| | |
| | (16) ...to here
| 1346 | if (l_num_entities < 2) {
| | ~
| | |
| | (17) following ‘false’ branch (when ‘l_num_entities > 1’)...
|......
| 1354 | pldm_entity *l_entities = calloc(l_num_entities, sizeof(pldm_entity));
| | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
| | |
| | (18) ...to here
| | (19) use of attacker-controlled value ‘(size_t)((int)*((char *)&*pdr + 10).num_children + 1) * 6’ as size without upper-bounds checking
|
```

However, rather than the relationship to pdr_len, the issue was the
confusion from the promotion from uint8_t to size_t. Teach the analyzer
about the UINT8_MAX limit explicitly.

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.
