* Implement binding and lowering for InterpolatedStringBuilder

This implements initial binding and lowering for the InterpolatedStringBuilder, used when an interpolated string is converted directly to a `string`, and not to some other builder type. I've written it in such a way as to make future refactorings to support general builder types simple, but some of the steps (particularly lowering) are more simplistic for now. I did _not_ implement nullable analysis or definite assignment in this PR, prototype comments have been left to make sure that those are handled later. The spec for this feature is located at https://github.com/dotnet/csharplang/blob/main/proposals/improved-interpolated-strings.md, I will have a PR out later today or tomorrow to reflect the changes from LDM earlier today.

This adds binding and lowering support for InterpolatedStringBuilderArgumentAttribute. For initial binding, we have an existing method that all argument binding goes through: CoerceArguments. However, lowering did not have a similar chokepoint, as every argument location started by calling `VisitList`, then `MakeArguments` at a later point. In order to ensure that the rewrite is handled correctly, I've done a refactor on `MakeArguments` to turn it into `VisitArguments` and update every place that handles arguments to instead use this new helper, which takes care of the rest of the argument rewrites (such as params) and will additionally update the receiver if needed.

* Unescape interpolated string literal components

Fixes #54703. Spec change is at dotnet/csharplang#4910.

Note that there is an interesting wrinkle here in that, for an interpolated string used as a string, the change in constant value makes the lowering mechanism an observable side effect. While doing this step during lowering instead of initial binding is technically feasible, it would be quite complex as there are several different ways an AppendLiteral call could get to lowering (dynamic, conversion to object, regular literal, passed by in, etc). For now, I'm opting for simple strategy of accepting this observable side-effect, and if we want to try and make that side effect invisble we can look at doing so at a later point.
