kernel: allow setting chainstate dbcache

Browse Source 
Add `btck_chainstate_manager_options_set_database_cache_bytes()` so Kernel callers can set the total database cache budget.
Use `uint64_t` for a fixed-width C API, reject values outside the architecture-specific range, and keep `DEFAULT_KERNEL_CACHE` as the fallback.
Apply the selected split to the block tree database and `LoadChainstate()`.
