CONTAINS predicate operator should test whether a string contains a substring

[qin9smile]

MGLSymbolStyleLayer can add predicate like this

but actually i want to use 'CONTAINS' , but it's crashed with error:
'NSInvalidArgumentException', reason: 'IN not supported for string comparison.'

maybe it's not support 'CONTAINS' ?

The SDK does support CONTAINS for determining whether an array contains a string. However, it doesn’t support CONTAINS for determining whether a string contains a substring. That’s blocked by mapbox/mapbox-gl-js#4113. Additionally, in v4.0.0-beta.3, it’s a known issue that this operator doesn’t work at all: #11013.
