Summary of changes

When an integration methods throws a MissingMethodException or MissingFieldException, disable the integration.

Reason for change

This scenario is most likely to occur when the app is trimmed (plus in some relatively obscure scenarios with binding redirects or strange deployments). In those cases, the exception will likely always be thrown, which could cause longer term issues. To fix, the customer should enable

Implementation details

Just as we do for "fatal" DuckTypeException or CallTargetInvokerExecption, disable the integration that generates the exception when this occurs.

Test coverage

I realised we don't have any tests (unit or integration) for the DuckTypeException behaviour, so added some, and added some for this behaviour too.

Other details

One slight issue came to mind. If we create a scope inside the OnBegin part of an integration, and then we hit this error, then we never close the scope, and will start leaking. I wonder if we could/should look to avoid that.

In the past, we only expected exceptions in the method when there were programming errors, so they should be relatively rare. But for trimming it's a different scenario, that's dependent on the customer, so maybe that's an issue?

Execution-Time Benchmarks Report ⏱️

Execution-time results for samples comparing the following branches/commits:

Execution-time benchmarks measure the whole time it takes to execute a program. And are intended to measure the one-off costs. Cases where the execution time results for the PR are worse than latest master results are shown in red. The following thresholds were used for comparing the execution times:

  • Welch test with statistical test for significance of 5%
  • Only results indicating a difference greater than 5% and 5 ms are considered.

Note that these results are based on a single point-in-time result for each branch. For full results, see the dashboard.

Graphs show the p99 interval based on the mean and StdDev of the test run, as well as the mean value of the run (shown as a diamond below the graph).

## Summary of changes

revert the revert of #6792
The missingMethodExceptions were most likely caused by a trimmed app
([see
discussion](https://dd.slack.com/archives/C07TBLYDQHX/p1741907211362359)).
We had some defense against this for _instrumented_ types, but not for
duck-typed types, and this is where the issue laid. This was taken care
of in #6807 for the generic case, and also after [talking with
DSM](https://dd.slack.com/archives/C069TJPTFPG/p1743500681812779), they
agree that we should try to instrument only user-defined protobufs, so I
excluded the microsoft protobufs (that were causing the issue). Thus,
this PR should be fine to merge as-is, even though it's best to merge it
after #6807 for maximum safety.
