FindTextInJars - implement search rules to support all fields from TextSearchQuery

[dos65]

In scalameta/metals#3093 we added a new endpoint - metals/findTextInDependencyJars.

Its request parameters model was copied from VS Code proposed API in order to switch the UI part of this search in VS Code extension to native one after this API become stable.

The issue is that the initial implementation respects only TextSearchQuery.pattern while other fields are ignored.
To complete this feature on server side we need to process isRegExp, isCaseSensitive, isWordMath fields too.
