Add AssertEx.EqualOrDiff

Fixes #34085

Fix netmodule build targeting net470 declaring a struct auto-getter

Fixes #34766

Previously, every instance of `LocalState` required allocation.  Now we use `BitVector`, which stores state information inline in the bits of a primitive.

With the previous implementation of `BitVector` (32 bits inline), only about 1.3% of our nullable tests require allocating any memory at all for nullable states.

However, I've updated `BitVector` to have 64 bits inline, and now only three of our tests require allocating memory for states.  Those three tests heavily exercise tuple conversions.
