[bitbake][PATCH 2/3] bitbake: fetch2/repo: add support for sync specific projects

["Sourabh Banerjee" <sbanerje@codeaurora.org>]

repo tool can fetch projects by name. I.e., if there are
multiple projects listed in the manifest file.

 <manifest>
  <project name="project1"  path="sync path1"  revision="sha256" />
  <project name="project2"  path="sync path2"  revision="sha256" />
 </manifest>

Documented Usage: repo sync [<project>...]

By supplying project=<project_name> recipe can choose to sync a specific
project.
Example:
  SRC_URI = "repo://REPOROOT;protocol=git;branch=main;manifest=default.xml;project=project1"

This is helpful when recipe needs to sync only a specific project
from a manifest that lists multiple projects.
