Support @typeInfo for 0.14.0

[lateefj]

The @typeInfo syntax has change for switch statements.

Looks good to me; however note that this would introduce an incompatibility with Zig 0.13.

As soon as 0.14 gets released, we will get this into main 👍 @lateefj thank you.

I found another compile error in examples with latest 0.14. I will just accumulate changes on this branch until release happens.

Only outstanding is related to TypeOf(anytype):

IIRC, types all got lower-cased for consistency; so it should be .pointer.
