feat: implement more software access properties

Software side effects implemented. This adds support for the following field properties:

• woclr
• woset
• rclr
• rset
• singlepulse
• onread
  • rclr All the bits of the field are cleared on read (field = 0).
  • rset All the bits of the field are set on read (field = all 1’s).
• onwrite
  • woset Bitwise write one to set (field = field | write_data).
  • woclr Bitwise write one to clear (field = field & ~write_data).
  • wot Bitwise write one to toggle (field = field ^ write_data).
  • wzs Bitwise write zero to set (field = field | ~write_data).
  • wzc Bitwise write zero to clear (field = field & write_data).
  • wzt Bitwise write zero to toggle (field = field ~^ write_data).
  • wclr All bits of the field are cleared on write (field = 0).
  • wset All bits of the field are set on write (field = all 1’s).
