core/mvcc: load table's rowid on initialization
...
We need to load rowids into mvcc's store in order before doing any read
in case there are rows.
This has a performance penalty for now as expected because we should,
ideally, scan for row ids lazily instead.

core/mvcc: persist writes on mvcc commit
...
On Mvcc `commit_txn` we need to persist changes to database, for this case we re-use pager's semantics of transactions:
1. If there are no conflicts, we start `pager.begin_write_txn`
2. `pager.end_txn`: We flush changes to WAL
3. We finish Mvcc transaction by marking rows with new timestamp.

core/mvcc: simplify mvcc cursor types
...
We have so many cursor types that it will be unbearable to properly make
all of them work. Let's simplify this and only focus on lazy cursor
which in the future will load from database in case we need it.

core/mvcc: Fix MVCC cursor traversal
...
Add an explicit rewind() to move to the beginning. Change forward()
semantics so that *after* first forward() call, you are pointing to the
first row, which matches the get_next_record() semantics in B-tree
cursor.

core/mvcc: Eliminate row generic types
...
The logging code that writes out transactions to disk needs to write out
the byte array that we actually use. The code is less hairly without the
generics so drop them.

database: fix an unwrap() in tx_commit
...
It was a legit error -> the transaction doesn't have to be active
when commit() is called on it, and the right behavior in that case
is to return a TxTerminated error.
