Bug 144094 – [cmake] Fix generate-js-builtins related incremental build issue

• Component: JavaScriptCore
• Status: RESOLVED FIXED

See https://bugs.webkit.org/show_bug.cgi?id=143980#c14 for details.

The root of the problem that cmake finds the input of generate-js-builtins
with *.js search. But the make/ninja doesn't know when the input list should
be regenerated and adding a new js can cause incremantal build fail.

I think we should teach generate-js-builtins to accept not only js files
as input, but an input directory where it can collects all of the js files
and we will be able remove *.js from cmake build system.

cc-ed Oliver and Michael as the original author and reviewer of
the generate-js-builtins script - http://trac.webkit.org/changeset/163195

I added the new --input-directory option to be able get rid of *.js
from cmake and let the python script to collect js files. But I didn't
remove the actual behaviour of the script, maybe somebody wants to
generate builtins for a couple of js not for all js in a directory.

Do you think if this change is acceptable to 
avoid incremental build issues in the future?
