Victor Stinner d83d26724b gh-152132: Test Py_CompileString() in test_capi.test_run (#153470 )

PyRun functions now raises ValueError if the start argument is
invalid.

* Add Modules/_testlimitedcapi/run.c.
* Rename _Py_CompileStringObjectWithModule() to
  _Py_CompileStringObject().

README.txt

Tests in this directory are compiled into the _testcapi extension.
The main file for the extension is Modules/_testcapimodule.c, which
calls `_PyTestCapi_Init_*` from these functions.

General guideline when writing test code for C API.
* Use Argument Clinic to minimise the amount of boilerplate code.
* Add a newline between the argument spec and the docstring.
* If a test description is needed, make sure the added docstring clearly and succinctly describes purpose of the function.
* DRY, use the clone feature of Argument Clinic.
* Try to avoid adding new interned strings; reuse existing parameter names if possible. Use the `as` feature of Argument Clinic to override the C variable name, if needed.
