Delegate creation with optional methods throw TargetParameterCountException when Dispatcher consumes

[Aytackydln]

Hopefully this is the correct repository to report. This behaviour is really annoying since you cannot find where this is caused from the exception trace since this is thrown in the consuming thread.

Version Used:
NET 8

Steps to Reproduce:

Dispatcher case code sample:
https://github.com/Aytackydln/OptionalParameterTaskWpf

1. Define a method with optional parameter
2. Pass it to an "async" method with only method name
   Like:
   Dispatcher.BeginInvoke(MethodWithOptionalParameter)
AsyncMethod(MethodWithOptionalParameter)
3. Let the dispatcher consume

Moving to runtime as this is not a compiler bug, it's about the exception information generated for this scenario.

Note: not a regression, tested this all the way back to net6.0 and observe the same behavior.
