[PATCH v2 4/5] sdk-manual: rename the section to remove "extensible"

The SDK manual covers both the standard and extensible SDKs yet the
title does not imply that, so rename the section to "Yocto Project
Application Development and the Software Development Kit (SDK) Manual".

As a consequence, rename the first section title and reword the intro.
