Add support for PostgreSQL array overlap operator (`&&`)

• Add support for PostgreSQL array overlap operator (&&) on array-typed properties:
  • "in" matchMode is automatically converted to "&&" in cleanFilters() when the property type is "array"
  • mapIndexes() now wraps indexes in ARRAY[...] for the "&&" matchMode, generating column && ARRAY[$1,$2]
  • mapComparator() now returns "&&" for the "&&" matchMode
  • "&&" added to Comparator type and COMPARATORS set
  • "array" added to MappedType; map.type() now maps entity type "array" to "array"
  • check.matchMode() now validates "&&" as the only allowed matchMode for array-typed properties
