meson: Build SWR driver

This enables the SWR driver, but doesn't actually hook it up to any of
the targets yet. I felt like this patch was big and complicated enough
without adding that.

v2: - Fix typo 'delemeited' -> 'delimited' (Eric E)
    - Fix type 'errror' -> 'error' (Eric E)
    - Use variables to hold files instead of looking above the current
      meson build (Eric E)
    - Use foreach loops to reduce the number of unique generators
    - Add comment about why some generators have names and some are just
      added to a list
v3: - Remove trailing whitespace
