Correct stability issues for SPOIDs for provisioning 4.0

[ Merge of http://go/wvgerrit/183472 ]

For provisioning 4.0 devices, the DRM certificate serial number
was changing on a reprovisioning attempt or factory reset. The
app parameters sent up in the client identification name-value
pair field were being filtered out in provisioning requests.
This has been corrected for provisioning 4.0 stage 2
(DRM certificate request). There is no need to include them for
stage 1 (OEM certificate request).

The test case WvCdmRequestLicenseTest.ProvisioningSpoidTest
was created earlier to ensure that SPOIDs and DRM certificates are
stable. Unfortunately due to another bug b/250099615, the RKP service
was holding a connection to the Widevine TA for provisioning 4.0
devices. When native tests ran as their own process, L1 would fail
to load due to a connection failure and the test would run as L3.
The tests passed for provisioning 4.0 devices Pixel 7 and 8 when
they should have failed. This gave us a false sense of confidence
that the SPOIDs were stable.

For now a workaround is to run a shell command to kill the widevine
TA before running native tests.

$ adb shell pkill -f -9 widevine

New tests have been introduced to provide integration coverage
WVPluginTest at the WV plugin level and CoreIntegrationTest
for core. GTS tests are also being written in b/295538002.
