Pass DSA_ALLOC_HUGE when allocating a shared TIDBitmap.
When creating an unshared TIDBitmap, we pass MCXT_ALLOC_HUGE to allow
allocations >1GB, so by analogy we pass DSA_ALLOC_HUGE for a shared
TIDBitmap.
Bug introduced by commit 98e6e89040a0534ca26914c66cae9dd49ef62ad9.
Report by Rafia Sabih, fix by Dilip Kumar, adjusted by me.
