Tonya Mork 648eb03768 WPDB: Capture error in wpdb::$last_error when insert fails instead of silently failing for invalid data or value too long.
Instead of silently failing when attempting to insert a value into a field, this commit saves the error in the `wpdb::$last_error` property.

Sets `last_error` with an error message if:
* `wpdb::query()` fails for invalid data
* `wpdb::process_fields()` fails to process the value(s) for the field(s) where the value could be too long or contain invalid data

Sets `last_query` if `wpdb::query()` fails for invalid data.

If `__()` is not available, uses non-translated error message to ensure the error is captured.

There is no change to wpdb aborting when an error occurs.

Adds tests.
