[chore][cmd/otelcontribcol] Re-enable exporters and receivers tests on Windows

[pjanotti]

Description:
Last part to re-enable all Windows tests disabled due to issue #11451.

Notes:

• The default test timeout is not enough for the cmd GROUP on CI and it was increased to 1200s just for this group on Windows, the default stays at 300s (which was also enough for my local run).
• The fileexporter life cycle test indicates an issue that shouldn't affect most usages of the collector: if the same configuration is used to export multiple signals it opens one file handle for each signal but just closes the one of them at shutdown (the helper only executes the shutdown for the one signal). This is an issue for the test because during cleanup the testing attempts to delete the test folder and there are still handles open to the file that lives inside it. This shouldn't be a problem for collector users. That said the exporter should close all file handles on shutdown. I will take look at what can be done to correct this behavior.
• Fixed a minor typo on the receivers test that affected many lines.

Fix #28679 - last part.

Testing:
Local run and GH CI on my fork with Run Windows label.

Thanks @pjanotti, any idea why the tests are 4x slower on windows?

Please take a look at the failing check:

Generated code is out of date, please run "make genotelcontribcol" and commit the changes in this PR.

@codeboten

I'm not sure at this point, but, I suspect the memory restrictions that are needed to run these tests on Windows GH runners:

opentelemetry-collector-contrib/.github/workflows/build-and-test-windows.yml

Lines 41 to 44 in 4beb5c1

	# Limit memory usage via GC environment variables to avoid OOM on GH runners, especially for `cmd/otelcontribcol`,
	# see https://github.com/open-telemetry/opentelemetry-collector-contrib/pull/28682#issuecomment-1802296776
	GOGC: 50
	GOMEMLIMIT: 2GiB

I'm planning to verify that.

I missed a required change in receiver\windowseventlogreceiver: its config type is different between the platforms. This PR should be broken until I fix that - doing as a separate PR to keep the history clean. Changing the current PR to draft until that one is fixed.

@codeboten my theory about GOGC=50 GOMEMLIMIT=2GiB GOMAXPROCS=2 didn't pan out in my box: it did take more than 300s but didn't need the the much larger one needed on GH. I will investigate that separately.

[pjanotti]

The extra long duration is due to the exporters test under cmd/otelcontribcol, in my box the exporter tests take around 70% of the time to run all tests in cmd/otelcontribcol.
