[build] Only link swiftIDEUtilsBridging when SWIFT_BUILD_SWIFT_SYNTAX is set

#70174 change swift-refactor and sourcekitd to not use `NameMatcher` from swift-syntax but it did not remove the link dependency from swiftRefactoring on `swiftIDEUtilsBridging` if `SWIFT_BUILD_SWIFT_SYNTAX` is false. Do so now.
