[🚀 Feature]: [dotnet] [bidi] Don't throw exception when CallFunction/Evaluate in Script module

[nvborisenko]

Feature and motivation

await context.Script.CallFunctionAsync("() => { return ['hi']; }", false);

It throws an .Net exception rather than returning EvaluateResult BiDi object.

script.EvaluateResult = (
  script.EvaluateResultSuccess /
  script.EvaluateResultException
)

Now, .Net methods throw if the result is EvaluateResultException. It is not ideal, low-level binding should not introduce additional logic on top of specification.

Why:

• We are hiding all data included into EvaluateResultException, trying to include it in .Net Exception type.
• If in future new derived type will be introduced in the spec (like "PartiallySuccess"), then we will be in **s (problematic situation)

Usage example

Before:

public Task<EvaluateResult.Success> CallFunctionAsync(...)

After:

public Task<EvaluateResult> CallFunctionAsync(...)

NOTE: Keeping in mind implicit/explicit type conversions in .NET.
