xgopilot 05da9ec252 fix: preserve Named interface type information through interface construction ...

This commit addresses the root cause identified in issue #1370 by preserving
Named interface type information through the interface construction phase.

**Root Cause:**
Named interfaces were prematurely unwrapped via Underlying() in the interface
construction phase (MakeInterface()/unsafeInterface()), causing the subsequent
ABI type generation to hit `case *types.Interface:` instead of
`case *types.Named:`, resulting in loss of package information.

**The Fix:**
1. Modified `unsafeInterface()` to accept a `namedIntf types.Type` parameter
2. Updated all callers to pass the Named type (tinter.raw.Type, assertedTyp.raw.Type, etc.)
3. When namedIntf is available, pass it to `abiType()` to ensure proper routing
   through the type switch to `abiNamedInterfaceOf()` which has correct package context
4. Reverted the workaround logic in `abiInterfaceOf()` that extracted pkgPath from methods

**Impact:**
- Fixes segmentation faults when calling interface private methods across packages
- Ensures runtime receives correct package path for interface metadata
- Allows private method slots in itab to be properly filled
