e4bca9649a Improved error spans for call errors: 
1. When calling a non-callable expression the error span is on the call target not on the whole call
2. When calling a method, the error for overload resolution now includes the arguments (this was previously regressed by #31414)

Allow JS with isolated modules (#31483) 
* Allow JS with isolated modules

Previously legacy JS code was not allowed; it was required to use ES6
module syntax. Unfortunately, the check happens after parsing but before
binding, and the commonjs module indicator isn't set until binding
because it's not syntactically simple like the ES6 module indicator,
which is set during parsing.

So I decided that JS should be allowed during isolatedModules
unconditionally. We're not going to be transforming it anyway.

* Update baselines

* Switch test to outDir instead of noEmit
