fix(tvix/eval): handle builtins.split matching the empty string r/8247
This prevents the following statements from looping endlessly: ``` builtins.split "(.*)" "" builtins.split "([abc]*)" "abc" builtins.split "(.*)" "abc" builtins.split ".*" "" ``` Cover these (and some more examples) in the test suite.
