In preparation for later changes to the workspace Symbol method, we add a separate configuration option keyed by "symbolMatcher" that specifies the type of matcher to use for workspace symbol requests. We also define a new type SymbolMatcher, the type of this new option. We require SymbolMatcher to be a separate type from Matcher because a later CL adds a type of symbol matcher that does not make sense in the context of other uses of Matcher, e.g. completion.
