Constructor for the class. Create a new preference filter entry with the given
key and match type. The key must not be null or empty.

Setting matchType to "prefix" treats the key as if it were a regular expression
with an asterisk at the end. If matchType is null, the key must be
an exact match.

key – the name of the preference key
matchType – specifies key match type, may be null to indicate
that exact match is required
