Like for Named types, print type parameters for Alias types.
Add test case for Alias object string to existing test.
To make the test work, factor out the mechanism to set
GOEXPERIMENT=aliastypeparams at test time and use it
for this test as well.
No test case for un-instantiated generic type Alias type
string: there's no existing test framework, the code is
identical as for Named types, and these strings only appear
in tracing output. Tested manually.

The Frames function is almost an iter.Seq, except for its bool return
value.
Since none of the callers in the Go tree rely on the bool, we can remove
it. However, doing so might still obscure the intended usage as an iterator.
This refactor changes the API to return iter.Seq, making the intended
usage explicit. Refactoring the existing callers to take advantage of
the new interface will be done in a follow-up CL.

MapIterNext-8 61.95n ± 0% 54.95n ± 0% -11.28% (p=0.000 n=10)
for the change of `test/escape_reflect.go`:
removing mapiterkey, mapiterelem would cause leaking MapIter content
when calling SetIterKey and SetIterValue,
and this may cause map bucket to be allocated on heap instead of stack.
Reproduce:
```
{
m := map[int]int{1: 2} // escapes to heap after this change
it := reflect.ValueOf(m).MapRange()
it.Next()
var k, v int
reflect.ValueOf(&k).Elem().SetIterKey(it)
reflect.ValueOf(&v).Elem().SetIterValue(it)
println(k, v)
}
```
This CL would not introduce abi.NoEscape to fix this. It may need futher
optimization and tests on hiter field usage and its escape analysis.
