1. Improve asExprOf cast error formatting (#19195) …

   The intention of this change is to make it simpler to read the error
   message.
   
   List the expected type and actual type before the expression. This is
   usually the most important information and simpler to parse as the
   expression can get quite long. For the expected type, the actual type
   and the expression, we print the value in the same line if its String
   representation has only one line. Otherwise we print it in the next line
   with an indentation and extra new line at the end.
   
   Before:
   ```
   java.lang.Exception: Expr cast exception: ((a: scala.Int) => ({
     val v: scala.Int = a
     Binding.apply[scala.Unit](())
   }: Binding[scala.Unit]))
   of type: scala.Function1[scala.Int, scala.Unit]
   did not conform to type: scala.Function1[scala.Int, Binding[scala.Unit]]
   
       at scala.quoted.runtime.impl.QuotesImpl.asExprOf(QuotesImpl.scala:76)
       ...
   ```
   
   Example from #19191
   
   After:
   ```
   scala.quoted.runtime.impl.ExprCastException:
     Expected type: scala.Function1[scala.Int, scala.Unit]
     Actual type: scala.Function1[scala.Int, Binding[scala.Unit]]
     Expression:
       ((a: scala.Int) => ({
         val v: scala.Int = a
         Binding.apply[scala.Unit](())
       }: Binding[scala.Unit]))
   
       at scala.quoted.runtime.impl.QuotesImpl.asExprOf(QuotesImpl.scala:...)
       ...
   ```
