sqlite3: updated to 3.31.1

SQLite Release 3.31.1:

Revert the data layout for an internal-use-only SQLite data structure. \ 
Applications that use SQLite should never reference internal SQLite data \ 
structures, but some do anyhow, and a change to one such data structure in \ 
3.30.0 broke a popular and widely-deployed application. Reverting that change in \ 
SQLite, at least temporarily, gives developers of misbehaving applications time \ 
to fix their code.
Fix a typos in the sqlite3ext.h header file that prevented the \ 
sqlite3_stmt_isexplain() and sqlite3_value_frombind() interfaces from being \ 
called from run-time loadable extensions.
