Move devtool doc from extensible to dev manual

[YOCTO #13417]

devtool is not directly tied to the Extensible SDK anymore, and
instructions in there can be split and added to the development manual.

This patch is a simple bulk move, except for the following:

- Intro added to the devtool.rst document (mostly copy-pasted from the
  devtool quick reference in the ref-manual).
- Figures renamed to remove "sdk-" from filenames.
- References to sdk-manual/extensible replaced by dev-manual/devtool.
