a11y: Add XAccessibleValue::getMinimumIncrement method
Add a method 'getMinimumIncrement' to the XAccessibleValue interface.
The method returns the minimal increment by which the value represented by
the object can be adjusted.
The main motivation is to expose this to AT-SPI, so it can be retrieved e.g.
by libatspi's 'atspi_value_get_minimum_increment' function [1],
s. the note in Change-Id: I8af326c2d24c1801147a56ea2e2a886ab42ac634
"a11y: Expose FormattedField as spinbox" for more details.
The implementation relevant for the 'FormattedField' class is in
'SVTXAccessibleNumericField::getMinimumIncrement', which returns
the spin size.
While at it, also move the comment in sw/source/core/access/acccell.hxx
mentioning what methods are overriden for the 'XAccessibleValue' interface
to the right place.
