refactor: change logic of threading control in CaseTester for MultiDev (RDT-534)

[horw]

Replaced logic of creating thread
before: new case every time create new thread
now: create thread once, and then thread wait for task
closes #184
closes #162

Hello, I've refactored thread depends code, now it works with generator functions

LGTM! The new approach looks good.

Still got some high-level problem.

The merged junit xml looks like this:

<testcase file="[group dev-0]: components/driver/test_apps/spi/master/main/test_spi_master.c&amp;lt;-------------------&amp;gt;&#10;[group dev-1]: components/driver/test_apps/spi/master/main/test_spi_master.c" line="[group dev-0]: 1603&amp;lt;-------------------&amp;gt;&#10;[group dev-1]: 1603" time="1.859" name="('esp32c6', 'esp32c6').('defaults', 'defaults').SPI_Master:Test multiple devices [dut-0]">
            <system-out>[group dev-0]:
                ... log ...
                &amp;lt;-------------------&amp;gt;
                [group dev-1]:
                ... log ...
        </testcase>

Got two places to improve:

1. [group dev-0] should be [dut-0] to keep consistence
2. The ---------- separator should not be used in attributes, like file, line

@ginkgm @L-KAYA PTAL as well.

After this PR got merged, the old case_tester used in ESP-IDF could be replaced by this unity_tester

The benefits of this approach are:

1. merged junit reports, with stdout (including performance data)
2. correct test case name even app got panic'ed
3. remove thread/process. Support multi OS.

Have went through the code, I love the idea of iterator! LGTM!

[hfudev]

LGTM. Let's drop the deprecation warning first, usually it's not a good idea to confuse users...

For the optimization of the timeout calculation, you may do it in a separate PR.

FAILED pytest-embedded-idf/tests/test_idf.py::test_dut_run_all_single_board_cases - AssertionError: assert 10.896 < 10.1

I've got this error in the pipeline, will check for it

p.s. problem was with device reset
