[r2dbc] OutboundRow class should not use deprecated class org.springframework.r2dbc.core.Parameter

[kdebski85]

org.springframework.data.r2dbc.mapping.OutboundRow class uses deprecated class org.springframework.r2dbc.core.Parameter. It was deprecated in Spring 6.0.

Documentation for org.springframework.r2dbc.core.Parameter says to use io.r2dbc.spi.Parameter instead, so OutboundRow should be changed to use the class from io.r2dbc.spi package.

Currently, OutboundRow users are forced to use deprecated org.springframework.r2dbc.core.Parameter class.

In order to preserve compatibility, maybe a new class similar to OutboundRow should be created which would use io.r2dbc.spi.Parameter.

It's indeed unfortunate that we still use deprecated API in OutboundRow. The new R2DBC Parameter SPI was inspired by Spring's API design so the actual change is switching packages and using a different factory API.

This is a change that we will have to apply in a future revision.
