twister: support namespacing of extra configs

[nashif]

We want to be able to have platform or architecture extra configs
without having to duplicate a whole section of the test specification.

This adds support for namespacing of extra configs, for example:

arch:nios2:CONFIG_SYS_CLOCK_TICKS_PER_SEC=1000

or

platform:qemu_x86:CONFIG_FOO=y

Works great! Could this be done for 'west build' too?

But west build only ever builds a single arch (for now) @keith-packard, unlike twister.

west has option --test-item where one can point to a particular scenario from yestcase/sample.yaml and west would build with using extra_args from yaml. I guess it can (or in fact should, for complementary?) updated as well.

yeah, I actually tried using west like this before I realized the patch was only to twister...

Could this namespacing feature be added to extra_args too?
Would be good to have something like this, rather than listing all KConfig options in the testcase.yaml file.

tests:
  drivers.flash.flash1234:
    platform_allow: native_posix_64 my_custom_board
    tags: drivers

    extra_args:       
      - platform:my_custom_board: "CONF_FILE=prj.conf;myboardoptions.conf"
      - platform:native_posix_64: "CONF_FILE=prj.conf"
