OFC filter: propertly like should be converted to sql expression for db layers

[assefa]

Right now when a filter encoding contains multiple PropertyIsLike? operations, it use MapServer class expressions to do the queries. But in some cases, we could converted them sql expression for db layers.

Here is an example of expression that should use sql expression for db layers:

<wfs:GetFeature xmlns:wfs="http://www.opengis.net/wfs" service="WFS" version="1.1.0" maxFeatures="100" xsi:schemaLocation="http://www.opengis.net/wfs  http://schemas.opengis.net/wfs/1.1.0/wfs.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><wfs:Query typeName="feature:HISTOMAP_NL_1799_English_Admiralty_region" srsName="EPSG:4326" xmlns:feature="http://mapserver.gis.umn.edu/mapserver"><wfs:PropertyName>LEGEND</wfs:PropertyName><wfs:PropertyName>NAME</wfs:PropertyName><ogc:Filter xmlns:ogc="http://www.opengis.net/ogc"><ogc:Not><ogc:PropertyIsLike wildCard="*" singleChar="." escape="!"><ogc:PropertyName>LEGEND</ogc:PropertyName><ogc:Literal>*open*</ogc:Literal></ogc:PropertyIsLike></ogc:Not></ogc:Filter></wfs:Query></wfs:GetFeature>
