test: Fixed nondeterministic failures in factoryTest()

[yonghanlin]

What does this PR do?

This PR fixes a nondeterministic test failure in FactoryTest.factoryTest() within . module when running with NonDex.

Problem

The nondeterminism occurs because the test randomly generates arguments for every create*() method. These arguments come from unordered collections and mixed element types, so their structure can change between runs.

Observed failures include:

• Invalid pattern nodes (CtTypePattern, CtUnnamedPattern) used outside of valid pattern-matching contexts (e.g., instanceof or switch).
• Null declaringType in CtField arguments, causing errors in methods like createVariableReads() or createVariableAssignments().
• Illegal record hosts (CtRecord) being used for constructs that records cannot legally contain.

Reproduce Test

To reproduce the failure, run NonDex on . module using the following commands:

mvn -pl . edu.illinois:nondex-maven-plugin:2.1.7:nondex -Dtest=spoon.test.factory.FactoryTest#factoryTest

The Fix

The fix introduces argument normalization before invoking each factory method:

1. Literal Replacement: Replace invalid pattern nodes (CtTypePattern, CtUnnamedPattern) with a harmless literal (CtLiteral(0)), which is a valid expression in all contexts.
2. Declaring Type Enforcement: If any CtField lacks a declaringType, attach it to a synthetic dummy host class (TmpHost_*) and ensure it has a valid type and simpleName.
3. Deep Normalization: Recursively traverse lists, arrays, and collections to normalize their contained elements (clone already-parented elements and replace illegal nodes).
4. Record Substitution: Replace CtRecord arguments with dummy classes when the target method requires a host that supports instance members.
5. Context-Specific Fixes: Special handling for createVariableReads and createVariableAssignments ensures that every nested field reference has a valid host.
