Init variables where they are declared when possible (clang-tidy)

clang-tidy -p compile_commands.json $file \
    -checks='-*,modernize-use-default-member-init,readability-redundant-member-init' \
    -config='{CheckOptions: [{key: modernize-use-default-member-init.UseAssignment, value: "1"}]}' \
    -header-filter='qtwayland' \
    -fix

Afterwards I ran search and replace on the diff to clean up some whitespace errors:

- Replaced '(\n\+[^:\n]*)(:\s+\+\s+)' with '$1: '
- Replaced '(\n\+[^,\n]*)(,\s+\+\s+)' with '$1, '
- Replaced '\n\+\s*\n' with '\n'

I also had to do some manual edits, because for some reason, this particular
clang-tidy check doesn't trigger for some files.
