Update GN toolchain_args to be a variable.

This makes toolchain_args on a toolchain definition a variable instead of a function call.

The function call is kept for backwards compatibility (for now) and it just sets the variable.

forward_variables_from now accepts a first parameter of any type that evaluates to a scope, which allows things like "invoker.toolchain_args" to be used there.

Updates "gn format" to format scope assignments without extra indents.
