Cuong Manh Le 2a4845257f cmd/compile: fix deadlock in (*Named).load 
For lazy import resolution, there's reentrancy issue with (*Named).load
method, when "t.resolve(t)" can lead us to the same named type, thus
(*Named).load is called recursively, causing the deadlock.

The main problem is that when instantinate a type, we calculate the type
hashing, including TParams. Calling t.TParams().Len() triggers the
reentrancy call to "(*Named).load".

To fix this, just not checking TParams().Len() if we are hashing.

Updates #48185
