refactor(tvix/value): hide internal string representation r/4482

Wraps the string representation in an additional newtype struct with a
private field in order to hide the representation from other modules.

This is done in order to avoid accidental leakage of the internals
outside of value::string.

In fact, this caught a mistake in the compiler module which was
directly constructing an internal variant.
