Remove Chinese Pinyin matching functionality

Browse Source 
Removed the `ToolGood.Words.Pinyin` package and all related
logic from the `Common.Search` project. This includes the
removal of the `ChinesePinYinSupport` property in the
`MatchOption` class and the associated `IsSimplifiedChinese`
method. Simplified the `StringMatcher` class by eliminating
Pinyin-based transformations and focusing solely on direct
fuzzy matching of input strings. These changes reduce
dependencies and streamline the codebase.
