[FIR2IR] Don't generate fake overrides for clashing synthetic properties

If a synthetic prop clashes with a real property (e.g. @JvmField
property from parent Kotlin class), don't generate fake override for the
synthetic property. This fixes a CONFLICTING_INHERITED_JVM_DECLARATIONS
error in a mixed hierarchy.
