fix: Cherry-pick DH-17537: Fix Advanced Filter dialog not showing the values list on tree tables

[vbabich]

Move isValuesTableAvailable getter from IrisGridTableModel to IrisGridTableModelTemplate to make it availalbe in tree table model. Fixes DH-17537 in enterprise.

Note, this doesn't fix the issue with Advanced Filter on tree tables in Community. JSAPI throws an exception on a treeTable.copy call.
