fix(sample-gen): allOf, oneOf lifting should consider properties and items

[mathis-m]

Description

relevant schema lifting util needs to consider properties and items.
the properties logic was already in place but was not used for array items. Have moved it to the lifting util so it gets used in any case.

Motivation and Context

Fixes #7040
Fixes #7042

This was introduced with v3.39.0 by my commit 0f541a1.
There anyOf and oneOf was first introduced to the sample generator for schemas other then array.items.anyOf | array.items.oneOf, unfortunately I did not handled the case were items or (properties in array.item schemas) are defined via anyOf or oneOf.

How Has This Been Tested?
