H5Ztrans: (feature) Improved H5Z_xform_noop() and H5Z_xform_create() … (#933)

* H5Ztrans: (feature) Improved H5Z_xform_noop() and H5Z_xform_create() function

- Made a small improvement for H5Z_xform_noop() function. Now,
  the function will also return TRUE if the data transform function
  expression = "x". For this case, the HDF5 library behaves in a
  similar fashion as the case when no data transform function has been
  specified.
- Improved the inline documentation of the function
  H5Z_xform_create() such it is more inline with the rest of the
  code.

* Committing clang-format changes

* H5Ztrans: (feature) Added 3 tests for improved H5Z_xform_noop() function

- Added serial test with data transform expression = "x" to
  verify the improved H5Z_xform_noop() function behaves as expected.
- Added 2 parallel tests with data transform expression = "x"
  in combination with a filter. Before, these tests will fail but
  with the improved H5Z_xform_noop() function they work and result
  in the expected behavior.
- Small bug fix for one of parallel filter tests.

* Committing clang-format changes

* H5Ztrans: (feature) Added release note about detection of the
           simple data transform function "x".

- Added a brief explanation about the implemented improvement
  of the detection of the simple data transform function "x"
  to the RELEASE.txt file.
