Several deployment-related changes

Remove .swift-version file (it's deprecated by Cocoapods), run deploy phase in CI using xcode 11.3, remove extra swift build in CI deploy phase (sourcekitten now runs it itself), remove deprecated skip_cleanup setting from CI config, remove test spec from podspec (since watchos doesn't have XCTest, we have to use --skip-tests flag with cocoapods anyway), adjusted swift_versions setting in podspec, add --deep flag to xcode signing to prevent some weird potential issues with xcode 11.
