feat: add features in get-dependent-files.ts

add logic to filter out spec file associated with the given component unit and all index files while getting all dependent files
add utlity function to get all the files (.html/stylesheets/.spec.ts) associated with the given component unit
change the constructor method of the class ModuleResolver (add 'rootPath' as an additional parameter)
