Reduce compilation time by dynamic registration.

Prior to this CL, the test generator will generate CTS and VTS test
files with TEST_F definitions for each spec file. This CL removes
all the generated source codes for test definitions by employing
dynamic registration:

* In each example file, each generated test model is registered to the
  TestModelManager from a dummy global variable initialization.
* Create value-parameterized test suites to instantiate generated tests
  from the registered test models.

Four test suites are affected:

* GeneratedTests.<test_name>
  -> TestGenerated/GeneratedTests.Test/<test_name>
* DynamicOutputShapeTest.<test_name>
  -> TestGenerated/DynamicOutputShapeTest.Test/<test_name>
* GeneratedValidationTests.<test_name>
  -> TestGenerated/GeneratedValidationTests.Test/<test_name>
* ComplianceTest.<test_name>
  -> TestGenerated/GeneratedComplianceTest.Test/<test_name>

Or in CTS

* ComputeMode/GeneratedTests.<test_name>/[0-2]
  -> TestGenerated/GeneratedTests.{Sync,Async,Burst}/<test_name>

This CL additionally fixes the issue that DynamicOutputShapeTest and
GeneratedValidationTests were missing from CTS.

This CL will reduce the NNAPI test compliation time.

Before:
$ rm -r generated/spec_* && specs/generate_all_tests.sh
$ m NeuralNetworksTest_static -j$(nproc)
  #### build completed successfully (02:27 (mm:ss)) ####

After:
$ rm -r generated/spec_* && specs/generate_all_tests.sh
$ m NeuralNetworksTest_static -j$(nproc)
  #### build completed successfully (58 seconds) ####
