build: Include various useful extensions in our built SQLite

It's the same list of extensions we use in our macOS nightly
builds currently:

  * COLUMN_METADATA
  * FTS3
  * FTS3_PARENTHESIS
  * FTS5
  * GEOPOLY
  * JSON1
  * MATH_FUNCTIONS
  * RTREE
  * SOUNDEX
  * STAT4

This commit doesn't add the function names to the SQLite Authorizer
white list, which can come later.  Live databases should be able to
use them immediately however.
