Feature: #83449 - Make list of fields configurable in Pagetree overview in Info module

See forge#83449

Description

The available fields in the module "Pagetree overview" in the Info module by default ship with the entries "Basic settings", "Cache and age" and "Record overview".

By using PageTsConfig it is now possible to change the available fields and add additional entries to the selectbox.

mod.web_info.fieldDefinitions {
    0 {
        label = LLL:EXT:info/Resources/Private/Language/locallang_webinfo.xlf:pages_0
        fields = title,uid,alias,starttime,endtime,fe_group,target,url,shortcut,shortcut_mode
    }
    1 {
        label = LLL:EXT:info/Resources/Private/Language/locallang_webinfo.xlf:pages_1
        fields = title,uid,###ALL_TABLES###
    }
    2 {
        label = LLL:EXT:info/Resources/Private/Language/locallang_webinfo.xlf:pages_2
        fields = title,uid,table_tt_content,table_fe_users
    }
}
Copied!

Next to using a list of fields from the pages table you can add counters for records in a given table by prefixing a table name with table_ and adding it to the list of fields.

The string ###ALL_TABLES### is replaced with a list of all table names an editor has access to.
