Description

This PR is a followup of qgis#48321

We can now populate the list of categories in the Classification renderer using the list of available classes for the selected attribute provided by qgis#48321

When classifying using the Classification attribute, categories are added only for the available classes, using our standard colors and translated descriptions for the 18 classes of the las spec, while random colors are used for the rest.

A new column showing the percentage of points within each class has been added.

User can set database without host and port, meaning he is using a service (tnsnames.ora)

The QGIS User Interface forced the port to not be empty even if the database is set and the host is empty.

It is an addition to qgis#39131 _[Oracle] Fix new connection greyed ok button_ to fix
qgis#38979 _Oracle - add/edit connection dialog forces hostname input - conflicts with Oracle Network Connection_
