base-hw: coding style

Improve consistency with the other base repositories, in particular

- Indentation of class initializers
- Vertical whitespace around control-flow statements
- Preferably place control-flow statements (return, break, continue) at
  beginning of a line
- Placing the opening brace of a namespace at the end of line
- Placing the opening brace of a class at a new line
- Removing superfluous braces around single statements
- Two empty lines between methods/functions in implementation files
