sqlite3: Add support for column metadata API

I found that Mono.Data.SQlite has a dependency on the column meta-data API, thus enabling this API enables use of Hibernate / Mono with SQLite and no doubt enables other ORMs / utility libraries.

ref: https://bugzilla.xamarin.com/show_bug.cgi?id=6333

The API is present in the used SQLite3 sqlite-autoconf-3080002 source-base. Thus we are enabling pre-existing SQLite support rather than introducing new code.

I am not aware of any issues that enabling this SQLite functionality introduces, other than a slightly increased library size of circa 1.5KB , i.e. coretexa9_vfp_neon i.MX6

- with column meta-data API        610360 libsqlite3.so.0.8.6
- without column meta-data API  608880 libsqlite3.so.0.8.6
