[Frontend] Add -public-autolink-library option (#35936)

Foundation imports CoreFoundation with `@_implementationOnly`,
so CoreFoundation's modulemap won't be read, and the dependent libraries
of CoreFoundation will not be automatically linked when using static
linking.

For example, CoreFoundation depends on libicui18n and it's modulemap has
`link "icui18n"` statement. If Foundation imports CoreFoundation with
`@_implementationOnly` as a private dependency, the toolchain doesn't have
CoreFoundation's modulemap and Foundation's swiftmodule  doesn't import
CoreFoundation. So the swiftc can't know that libicui18n is required.

This new option will add LINK_LIBRARY entry in swiftmodule to
specify dependent libraries (in the example case, Foundation's
swiftmodule should have LINK_LIBRARY entry of libicui18n)
