[jax2tf] Add converted primitives without tests to the generated doc. (#4248)
* [jax2tf] Add converted primitives without tests to the generated
doc.
* Ignore some primitives in the output of untested primitives.
* Added control_flow_ops_test to template and updated primitives.
* Removed svd from the list of missing tests.
Was just included because I run the tests using
JAX_SKIP_SLOW_TESTS=1, which didn't run the SVD tests. Patched
the generated file manually.
