feat(go/adbc/driver): initial tracing instrumentation for Snowflake driver

[birschick-bq]

Includes some improvements to ease instrumentation
Instrumentation for the Snowflake driver.

Example

func (base *ImplementsAdbcOTelTracing) MyFunction(ctx context.Context) (nRows int64, err error) {
    nRows = -1

    ctx, span := utils.StartSpan(ctx, "MyFunction", st)
    defer func() {
        // Optionally set attributes before exiting the function
        span.SetAttributes(semconv.DBResponseReturnedRowsKey.Int64(nRows))
        // MUST call this to ensure the span completes
        utils.EndSpan(span, err)
    }()
}

@zeroshade - Matt

Just made a couple of small changes to ensure the error is set correctly before returning from functions, so that tracing has the correct error instance.

Note that snowflakedb/gosnowflake@d092186 (which is in 1.14.1 that I just merged) adds OTel to the Snowflake SDK, if we can confirm this works with that
