MF standard sequences cleanup

[namapane]

PR description:

• Get rid of MagneticField_38T_PostLS1_cff, which has been deprecated ages ago;
• fix ConfigBuilder.py to use the standard MF sequence. As of now, and for data only, it was forcing loading of MagneticField_AutoFromDBCurrent_cff which anyhow points to the standard sequence.

Note that the latter fix removes a meaningless warning message from ConfigBuilder.py as well.

These changes have been recently discussed in #31651 (comment)

Note: a significant number of instances of MagneticField_AutoFromDBCurrent_cff is still present in cfg files all around. A good fraction is being handled in #31788; others will be a subject of future PRs, before we can finally remove that cff.

PR validation:

Changes are trivial; ie replacing obsolete sequences with others that load exactly the same field map.
