update MOM6 to its main repository 20240228 commit

[jiandewang]

This is a big PR which originally was GFDL 20231113 candidate PR (mom-ocean/MOM6#1616).
The original PR failed to retain UFS BL on wcoss2 but are fine on all other platforms. With Marshall and Bob's further modification, it can retain UFS BL on wcoss2 for 1x1, half and quarter degree settings now. Discussion on the root cause of the original failing of retain BL can be found in the original PR (mom-ocean/MOM6#1616) and the last commit from Marshall in ths PR.
new BL are needed for:

• cpld_control_c48: two new variables are being added in this setting (p_surf_EOS=True), this is why you will see all files are OK in cmp except ocean restart files on all platforms (except wcoss2). For wcoss2 it changed answers.

• hafs_regional_storm_following_1nest_atm_ocn_wav_mom6: a bug fixing is included which changed answer in this PR

note the original DEFAULT_2018_ANSWERS=T has changed to DEFAULT_ANSWER_DATE=20181231 in MOM_input
