[SH] Enable shrink-wrap with reorder_blocks_and_parition

[Christian Bruel]

Hi Kaz,

Now that the cross-jumping problem is fixed since rev #193350, I'd like
to remove this restriction and close PR/54546.

Checked with default sh-sim target_board and
--target_board=sh-sim/-freorder-blocks-and-partition.

Thanks

Christian
