Prepere repo so we can run auto formatters (#747)

* clang-format: Ignore javascript files

Ignore javascript files. Clang-format is not very good formatter for
javascript files anyway. If we ever need javascript formatter we should
use Prettier.

* clang-format: Ignore some lines in sources

Couple things get formatted really funky if we let clang-format format
those. Just ignore those locally.

* zephyr/tescase.yaml: Fix yaml syntax

pre-commit hook check-yaml did found out that there are two skips.
Remove another as this is not right syntax.

* Fix repo contains unicode replacement chars

When running pre-commit text-unicode-replacement-char it founds that
there is couple unicode replacemnt chars. Remove and replace these.

* Convert some tabs to spaces manually

We will soon auto format tabs to spaces. How ever it could not do couple
thing so fix those by hand first.

* Make files with shebang executables

It is good habit that if file has shebang then it is marked executable.
These where found with pre-commit check-shebang-scripts-are-executable
checker.
