Drop P_DIRTY, and MDB_WRITEMAP dirty/spill lists

mt_workid = mt_txnid when WRITEMAP, so dirty pages == "spilled"

mp_txnid = page state, avoids searching dirty_list
...
In nested txns, check mp_txnid to see which txn dirtied the page.
This change will also let us remove the P_DIRTY flag, and keep
some flags in (dirty page).mp_txnid if we should need it.

Divide page flags in P_ADM_FLAGS and the rest
...
P_ADM_FLAGS flags are tied to the page, even through page_loose-alloc.
OTOH mdb_page_split() should only duplicate the relevant flags.
This is just the code for the feature, P_ADM_FLAGS is 0 for now.
We'll need it for P_HIDESPILL later.
