[benchmark] Change the swiftpm pm package to conditional ObjectiveCNoBridgingStubs on Xcode and SWIFT_PACKAGE.
[benchmark] Change the swiftpm pm package to conditional ObjectiveCNoBridgingStubs on Xcode and SWIFT_PACKAGE.

Otherwise while xcrun swift build will work, a generate xcodeproject from
swiftpm will not.
