cmake.m4: Update Autoconf macros documentation

Browse Source 
This updates the documentation for the CMAKE_FIND_BINARY and
CMAKE_FIND_PACKAGE Autoconf macros to imitate other Autoconf macros
internal documentation style with some stylistic adjustments for
readability of the arguments.

- CMAKE_FIND_PACKAGE: Links to docs are added instead of listing
  compiler IDs. The 5th ($5) and 6th ($6) arguments descriptions are
  updated to be action-if-found and action-if-not-found according to the
  current code.
