PrepareSortSupportFromIndexRel() was accepting btree strategy numbers purely for the purpose of comparing it later against btree strategies to determine if the sort direction was forward or reverse. Change that. Instead, pass a bool directly, to indicate the same without an unfortunate assumption that a strategy number refers specifically to a btree strategy. (This is similar in spirit to commits 0d2aa4d4937 and c594f1ad2ba.) (This could arguably be simplfied further by having the callers fill in ssup_reverse directly. But this way, it preserves consistency by having all PrepareSortSupport*() variants be responsible for filling in ssup_reverse.) Moreover, remove the hardcoded check against BTREE_AM_OID, and check against amcanorder instead, which is the actual requirement.
