cmd/compile: report error instead of ICE for oversized map element
When a map element or key type is 2GB or larger, the compiler crashed
with "internal compiler error: map elem too big" in reflectdata.ZeroAddr.
Add a size check in types.CalcSize for TMAP, similar to the existing
check for channel element types, so that oversized map elements are
reported as a normal error before reaching ZeroAddr.
Fixes #78355
