tests: i2c: i2c_target_api: added single mode testcase

[CZKikin]

Some drivers do not support dual mode testcase. It would be great to test both signle and dual mode, even when the drivers do support this feature.

I would not recommend to enable test this way, as the board to board loopback testing is not that reliable, instead can you enable i2c_ram test through the ardiono_i2c? but this is not a blocking for this PR.
besides, I test below platform:
mimxrt1170_evk/mimxrt1176/cm7 for i2c_mcux_lpi2c
frdm_mcxn947/mcxn947/cpu0 for i2c_mcux_flexcomm
which all works fine.

so my recommandation would be to add the mimxrt1170_evk/mimxrt1176/cm7 and mimxrt1170_evk/mimxrt1176/cm4 in this PR as well.

@CZKikin, please address your CI issues

a bit premature on the +1, ci needs to be fixed

[hakehuang]

@CZKikin add mimxrt1170_evk/mimxrt1176/cm7 overlay, but do not remove the mimxrt1170_evk@B/mimxrt1176/cm7

[hakehuang]

board testing is PASS for all supporting platforms, but need fix the CI issue @CZKikin
