refactor(grid): remove advanced filtering parameters

[adrianptrv]

Closes #15997

Depends on: #461

The following four parameters are still used for styling the Excel-style filter and Filtering row:
$filtering-header-background,
$filtering-header-text-color,
$filtering-row-background,
$filtering-row-text-color

I removed the following four parameters, as they are no longer used for styling the advanced filtering dialog:
$filtering-background-and
$filtering-background-and--focus
$iltering-background-or--focus
$filtering-background-or

The advanced filtering dialog is now styled using the query-builder theme.
Both the docs and the sample have been updated to use the query-builder theme.
