Adding "Field Calculator" menu item to the attribute table header

PR Description:

Description

Added a new "Field Calculator" menu item in the popup appearing when right clicking in the header of a column in a vector layer's attribute table. The Field Calculator window opens having the "Update existing field" checkbox checked and the corresponding field already selected in the combo box.

The action is enabled or disabled according to the field's possibility to be edited.

This is done by passing an optional field index parameter to QgsFieldCalculator::QgsFieldCalculator constructor (defaults to -1 if null). That makes it like a nice shortcut instead of clicking to open the Field Calculator, then checking "Update existing field" then selected the appropriate field name.

Fixes qgis/QGIS#55266.
