test: fix broken env fuzzer by initializing process

[AdamKorcz]

Fixes a broken fuzzer.

It looks like the fuzzer is leaking memory, but it is so slow that it is hard to tell. Once the fuzzer starts running on OSS-Fuzz again, we should get good feedback. If it has a leak, then I plan to fix it over the next couple of weeks; If anyone can spot a possible leak without running it, it would be a great help.

LGTM though I do wonder why this is not using node::InitializeOncePerProcess() instead..

Actually I just noticed that it seems the fuzzers aren't tearing down the platform etc. properly. See

node/test/cctest/node_test_fixture.cc

Lines 36 to 43 in b68fa59

	void NodeTestEnvironment::TearDown() {
	cppgc::ShutdownProcess();
	v8::V8::Dispose();
	v8::V8::DisposePlatform();
	NodeZeroIsolateTestFixture::platform->Shutdown();
	NodeZeroIsolateTestFixture::platform.reset(nullptr);
	NodeZeroIsolateTestFixture::tracing_agent.reset(nullptr);
	}

for an example

Thank you for the feedback. I will test this and make a follow-up PR.
