Richard Smith 8b59e85b16 Add support for inline Cpp declarations. (#6994)
For #6830, add support for inline C++ fragments as a declaration rather
than as a packaging directive. For now, this uses `inline Cpp
<string-literal>;` as syntax. The prior `import Cpp inline
<string-literal>;` is left alone for the time being. We can decide
separately whether to remove that.

`inline Cpp` requires that there was at least one `import Cpp`. It's not
clear to me if that's the right design long-term, but it seems
reasonable for now.

Nicholas Bishop 1ef35e8299 Fix name mangling for Carbon functions called from C++ (#6984)
Since this requires using the `Mangler` class from `toolchain/check`,
moved it from `toolchain/lower` to `toolchain/sem_ir`.

The mangled name is then attached to the `FunctionDecl` with an
`AsmLabelAttr`.

Nicholas Bishop 85da6cae01 Support calling simple Carbon functions from C++ (#6967)
For now, only functions with no parameters and a `()` return type are
supported.
