In BF-11716, the second task in the stitch_support_lib_build_and_test task group (stitch_support_run_tests) is failing because it gets run on a different build variant (and at the same time as, rather than after) it's dependency task (stitch_support_install_tests). We should set max_hosts to 1 on the stitch_support_lib_build_and_test task group so these tasks get run in consecutive order on the same host.

Similarly, in BF-14342, embedded_sdk_install_dev is getting run before it's dependency task (embedded_sdk_build_cdriver). These tasks are run as part of the embedded_sdk_build_and_test task group.

User story:
As a server engineer,
When I run the stitch_support_lib_build_and_test and embedded_sdk_build_and_test task groups, I should know that each task group's tasks will get run in consecutive order on the same host, so that I do not have failures in my build.

AC:

• Tasks within the stitch_support_lib_build_and_test task and the embedded_sdk_build_and_test task groups should run in consecutive order
