clang-format: copy latest and re-format

clang-format-16 has some backwards incompatible changes that require
additional settings for best compatibility and re-running the formatter.
Copy the latest .clang-format from the docs repository[1] and reformat
the repository.

[1] https://gerrit.openbmc.org/c/openbmc/docs/+/63441

Further, shift the fixup for C's `_Static_assert` into src/msgbuf.h to
prevent a clang-tidy-16 error:

```
/data0/jenkins/workspace/ci-repository/openbmc/libpldm/src/msgbuf.h:315:2: error: '_Static_assert' is a C11 extension [clang-diagnostic-c11-extensions,-warnings-as-errors]
        _Static_assert(sizeof(*dst) == sizeof(ldst),
        ^
```

And fix up the function prototype in the definition of `pldm_open()`:

```
../src/requester/pldm.c:128:16: error: a function declaration without a prototype is deprecated in all versions of C [clang-diagnostic-strict-prototypes,-warnings-as-errors]
void pldm_close()
               ^
                void
```
