Removing crt waitForNoResources

[RanVaknin]

Motivation and Context

The AWS SDK Java tests currently use CrtResource.waitForNoResources() in teardown methods to verify proper cleanup of CRT resources. This method blocks execution until all resources are released or until a hardcoded 60-second timeout occurs.

We're experiencing frequent intermittent test failures in integration tests due to this timeout being reached:

[ERROR] Tests run: 7, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 60.36 s <<< FAILURE! -- in software.amazon.awssdk.http.crt.AwsCrtAsyncHttpClientSpiVerificationTest
[ERROR] software.amazon.awssdk.http.crt.AwsCrtAsyncHttpClientSpiVerificationTest -- Time elapsed: 60.36 s <<< ERROR!
java.lang.RuntimeException: Timeout waiting for resource count to drop to zero
	at software.amazon.awssdk.crt.CrtResource.waitForNoResources(CrtResource.java:448)8)

This PR removes all instances of CrtResource.waitForNoResources() from test teardown methods to prevent these intermittent failures. The standard resource cleanup through close() methods will still occur, but we will no longer wait for or validate complete native resource cleanup.

Alternatively, we can just catch these exceptions:

@AfterClass
public static void tearDown() {
    client.close();
    try {
        CrtResource.waitForNoResources();
    } catch (RuntimeException e) {
        // log the exception or do somethging else
    }
}
