cmd/compile: fix width not calculated for imported type
The compiler currently has problem that some imported type is missing
size calculation. The problem is not triggered until CL 283313 merged,
due to the compiler can compile the functions immediately when it sees
them, so during SSA generation, size calculation is still ok.
CL 283313 makes the compiler always push functions to compile queue,
then drain from it for compiling function. During this process, the
types calculation size is disabled, so calculating size during SSA now
make the compiler crashes.
To fix this, we can just always calculate type size during typechecking,
when importing type from other packages.
Fixes #44732
