Subject: Don't use env vars for configuration time options

- As a general rule of thumb one shouldn't use environment variables
  for setting configuration options for CMake. The reason for this is
  we don't know when CMake will be executed and re-evaluate that variable.
- e.g. If we run cmake a first time with a var set, and then run make on
  a second session (with no var) and cmake is called because a
  dependency changed, the option would be disabled
- This commit removes the use of environment vars from
  src/nvim/CMakeLists.txt entirely
- Removed SKIP_UNITTEST since it could only be used to remove a target
  at configuration time (and the target was optional anyway)
- Turned SANITIZE into an option, clang-asan.sh now passes cmake
  -DSANITIZE=ON
- Removed SKIP_EXEC since it was disabling a target at configuration time
  (not being used)
