kernel: Add chainstate load options for in-memory dbs in C header
This allows a user to run the kernel without creating on-disk files for
the block tree and chainstate indexes. This is potentially useful in
scenarios where the user needs to do some ephemeral validation
operations.

One specific use case is when linearizing the blocks on disk. The block
files store blocks out of order, so a program may utilize the library
and its header to read the blocks with one chainstate manager, and then
write them back in order, and without orphans, with another chainstate
maanger. To save disk resources and if the indexes are not required once
done, it may be beneficial to keep the indexes in memory for the
chainstate manager that writes the blocks back again.
