cmake: reformat/update install targets

Cleanup the formatting and add component for each build target.
The latter will allow us to use CPack to create a component
based installer for Windows.
Additionally install wflinfo to CMAKE_INSTALL_BINDIR rather
than hardcoding it to 'bin'.

v2: Tag html documentation as htmldocs COMPONENT. Suggested by Chad.
