Lower CppOverloadSetValue (#6101)

Browse Source 
Following up on comments from
[#5891](https://github.com/carbon-language/carbon-lang/pull/5891) ([
1](https://github.com/carbon-language/carbon-lang/pull/5891#discussion_r2317244981),
[2](https://github.com/carbon-language/carbon-lang/pull/5891#discussion_r2317266756)).

Lowering `CppOverloadSetValue` as an empty struct value, using
`context.GetLiteralAsValue()`. Also changed its constant kind to
`InstConstantKind::Always`.
