tools/gopls: add cmd support for workspace_symbol
This change adds command line support for workspace/symbol.
Symbols are formatted as '{span} {name} {type}'.
$ gopls workspace_symbol -matcher fuzzy 'wsymbols'
$
$ workspacesymbol/a/a.go:5:7-31 WorkspaceSymbolConstantA Constant
$ workspacesymbol/b/b.go:5:6-28 WorkspaceSymbolStructB Struct
Optional arguments are:
-matcher, which specifies the type of matcher: fuzzy, caseSensitive, or caseInsensitive.
The default is caseInsensitive.
Updates golang/go#32875
