Don't assign the normalEvaluator per default (#4548)

* Don't assign the normalEvaluator per default

Assigning the normal evaluator to theEvaluatorFunction means that it
always needs to be exported.

CSP doesn't use the normalEvaluator and should not include it in any
build. alpinsjs/src/index.js always assigns the normalEvaluator manually
and works as expected, and it isn't included anymore in the csp builds.

* normalEvaluator also needed dependencies for unsafe functions which we
  don't want to include in the csp build

* Generate sourcemap files for the generated files

+ it would really helpfull for developers to have sourcemap files alongside of the js and minified js files

* Review fixes: remove unrelated sourcemap addition from build.js

The sourcemap change is unrelated to the CSP evaluator fix and
should be a separate PR if desired.
