Isolate setTimeout bridge key as a shared constant

[AngelaVilladiego]

Dedupes the "setTimeout" string literal used as the forKeyedSubscript key for the JSContext polyfill.

Changes:

• JSUtilities.swift: added static let setTimeoutKey: NSString = "setTimeout"
• SwiftUIPlayer.swift teardown + JSUtilitiesTests.swift: reference the new constant instead of the literal
