[AArch64][GlobalISel] Add some more legal types for G_PHI, G_IMPLICIT_DEF, G_FREEZE.
Also use this opportunity start to clean up the mess of vector type lists we have in the LegalizerInfo. Unfortunately since the legalizer rule builders require std::initializer_list objects as parameters we can't programmatically generate the type lists.
