OESS-330/HDFFV-11282: Improve failure message when a VOL connector can't be loaded (#2481)

Browse Source 
* OESS-330/HDFFV-11282: Improve failure message when a VOL connector can't be loaded.  Made the error message clearer when the library can't find a plugin in the path table that contains the paths set by HDF5_PLUGIN_PATH and the default location and maybe set by H5PLxxx functions.

* Committing clang-format changes
