* pre-commit: Update and enable clang-format check
There is newer version from clang-format so use that. We do not yet want
18 as that is little bit too new.
* Format some thing by hand which clang-format "breaks"
Clang-format will format some things little bit off in some cases.
Format some things by hand so we get cleaner end result.
* Run clang-format with
```
pre-commit run --all-files clang-format
```
We have already in previously checked places where clang-format does not
make good format and ignored those (hopefully most of the things).

* Change MIT license texts to SPDX-License-Identifier
SPDX-License-Identifier is much easier to understand and grep than
license text so use that instead.
* Change GPL exception license texts to SPDX-License-Identifier
SPDX-License-Identifier is much easier to understand and grep than
license text so use that instead.
* Change misc license texts to SPDX-License-Identifier
There are some external code in repo which are not licenses as most of
the stuff in this repo. We still want every file to have SPDX identifier
to easily grep licenses.
* Add currently used license files
Even though Bacnet-Stack is using SPDX identifiers we still need to give
those license files with source. For this reason add all license files
to license/ folder.
SPDX has also files which would make same thing but this is style which
example Linux kernel is using and it is quite clear so I choose that one
for now.
I choosed not yet bring CC-PDDC as that is not right license for those
files.
