Refactor handle kinds into a table and mark the static base address cell handle non-null

[SingleAccretion]

There are two parts to this change:

1. Centralizing knowledge about handles into a table (like with e. g. intrinsics). This is no-diff.
2. Marking GTF_ICON_STATIC_ADDR_PTR as producing non-null values. This handle type is used for NAOT GC static bases which are initialized at startup. This part has some minor positive diffs on NAOT.
