Fixes to EGL.functional.hdr_metadata.* tests

- Adjust given values to fit uint16_t (range used in smpte2086
  and cta861.3 specs).

- Allow EGL_BAD_PARAMETER error happen when setting parameters,
  per spec this means values passed are not supported by the
  implementation. Output attribute and given values in this
  case for debugging purposes.

v2: skip unsupported but check supported attributes (Courtney)
