because any changes to them made after that point would have no
useful effect.
This function bootstraps only the _synchronous_ pieces of the
library. After calling this, sqlite3.asyncPostInit() must be
called to initialize any async pieces (most notably the
OPFS-related pieces) and should then delete sqlite3.asyncPostInit.
That function is NOT part of the public interface, but is rather a
side-effect of how we need to finalize initialization. If we
include that part of the init from here, this function will need to
return a Promise instead of being synchronous.
This function returns a Promise to the sqlite3 namespace object,
which resolves after the async pieces of the library init are
complete.
