[lite] Don't skip tests that need feedback vector in lite mode

Tests that expect type feedback vector ensure it by using
%EnsureFeedbackVector intrinsic. These tests now work with lazy feedback
allocation as well. Hence it is no longer required to initialize the
shared function info with a special bailout id.
