Also, fixes an issue where forced single-line formatting would break for if/else
and let expressions

This changes code so that multiple lambda arguments makes the whole
argument list wrap.
Improves the readability of code like:
```
foo
.toMap(
(it) -> makeSomeKey(it),
(it) -> makeSomeValue(it)
)
```
This forces iterpolated expressions to be single-line, so that newline
literals within the bounds of two string delimiters can be seen as
verbatime newlines in the resulting string.
Edge case: in the case of a line comment, it's not possible to keep
this as a single line expression.
These are kept as multi-line expressions.
Also:
* Remove `ForceWrap`, this node is not used.
* Rename `StringConstant` -> `StringChars`
This changes the formatter to only force line on call chains
with multiple lambdas
With this change, this is kept as a single line:
```
foo.bar.map((it) -> it + 1)
```
