Paul Jolly ca5866bcf9 internal/lsp: add config option for SymbolMatch
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.
