Add: Add Plugin for variable redefinition in foreach loop

[ghost]

What

This pr adds a plugin to check if a variable is redefined by using the same variable name for the list and the element being iterated over.

foreach foo(foo){}

Why

Using the foreach for redefinition is valid code, but is more likely a typo than intended for normal VT development.
The foreach loop will also not throw an error if the list variable does not exist and is initialised as an empty list instead.
Should be reported:

urls = make_list( "/foo", "/bar" );
foreach url( url )

-> Typo in the second "url" variable

url1 = make_list( "foo", "foo2" );
url2 = make_list( "bar", "bar2" );
foreach url(make_list(url1 , url))

-> Probably a typo in the second "url"

url1 = make_list( "foo", "foo2" );
url2 = make_list( "bar", "bar2" );
foreach url(make_list_unique(url1 , url))

-> Probably a typo in the second "url"
