Lint and format context receiver

[paul-dingemans]

Description

Change indent rule to accodomodate for the context receiver list. Add new rule content-receiver-wrapping to wrap a context receiver to a separate line regardless of the max line length setting, and, wrap context receiver and type projections to separate lines when max line length is exceeded.

Some example of code after auto correct:

    // ALways wrap regardless of whether max line length is set
    context(Foo)
    fun fooBar()

    // Wrap each context receiver to a separate line when the
    // entire context receiver list does not fit on a single line
    context(
        Fooooooooooooooooooo1,
        Foooooooooooooooooooooooooooooo2
    )
    fun fooBar()

    // Wrap each context receiver to a separate line when the
    // entire context receiver list does not fit on a single line.
    // Also, wrap each of it projection types in case a context
    // receiver does not fit on a single line after it has been
    // wrapped.
    context(
        Foooooooooooooooo<
            Foo,
            Bar
            >
    )
    fun fooBar()

Closes #1672
