Rename test suite to a more correct CorbAndCorsExtensionBrowserTest.

Motivation for the changes in the CL:

- "Allowlisting" in the old test suite name focused on only 1 out of 4
  parameters that the test cases are parametrized with (kAllowlisted,
  kOutOfBlinkCors, kAllowlistForCors, kDeriveOriginFromUrl).

- "CrossOriginReadBlocking" focused only on CORB, when the test cases
  have already been covering also CORS (e.g. when covering the
  CorbAllowlistAlsoAppliesToOorCors feature).

Changes in the CL:

- The CrossOriginReadBlockingExtensionAllowlistingTest test suite is
  renamed to CorbAndCorsExtensionBrowserTest.  This test suite is
  parametrized (see TestParam enum).

- The CrossOriginReadBlockingExtensionTest test suite is renamed to
  CorbAndCorsExtensionTestBase.  Most methods of the test suite
  are moved to the parametrized test suite (i.e. to
  CorbAndCorsExtensionBrowserTest).  InstallExtension method from
  the base and from the derived class is flattened.  InstallApp method
  is moved/inlined into the WebViewContentScript test case.

- The following tests are moved from the non-parametrized test suite
  to the parametrized one:
    - FromBackgroundPage_NoSniffXml
    - FromForegroundPage_NoSniffXml
    - FromServiceWorker_NoSniffXml (note https://crbug.com/1051594)
    - ProgrammaticContentScriptVsWebUI
  Only the WebViewContentScript test case remains to be
  non-parameterized.
