[Frontend/Serialization] Narrow -swift-compiler-version to -interface-compiler-version

Browse Source 
It might be unexpected to future users that `-swift-compiler-version`
would produce a version aligned to .swiftinterface instead of one used
to build the .swiftmodule file. To avoid this possible confusion, let's
scope down the version to `-interface-compiler-version` flag and
`SWIFT_INTERFACE_COMPILER_VERSION` option in the module.
