feat: flexible choices for run_all_single_board_cases

[horw]

The Unity test framework itself supports different inputs for choice tests. This merge request emulates this behavior to make it possible to control test choices with pytest-embedded.

The current ways to choose tests are:

• group
• groups
• invert group
• name
• attributes

For example:

2024-04-26 16:35:17 Here's the test menu, pick your combo:
2024-04-26 16:35:17 (1)	"can use static initializers for non-POD types" [restart_init]
2024-04-26 16:35:17 (2)	"static initialization guards work as expected" [misc]
2024-04-26 16:35:17 (3)	"global initializers run in the correct order" [misc]
2024-04-26 16:35:17 (4)	"before scheduler has started, static initializers work correctly" [misc]
2024-04-26 16:35:17 (5)	"init_priority extension works" [misc]
2024-04-26 16:35:17 (6)	"can use new and delete" [misc]
2024-04-26 16:35:17 (7)	"can call virtual functions" [misc]
2024-04-26 16:35:17 (8)	"can use std::vector" [misc]
2024-04-26 16:35:17 (9)	"stack smashing protection CXX" [stack_smash]

1. choose all (1-9):
   dut.run_all_single_board_cases()
2. choose by group(2-8):
   dut.run_all_single_board_cases(group="misc")
3. choose by inverting group(1,9):
   dut.run_all_single_board_cases(group="!misc")
4. choose by name(9):
   dut.run_all_single_board_cases(names=["stack smashing protection CXX"])

addition examples:
dut.run_all_single_board_cases(group="heap,mem_prot") # [heap][mem_prot]
dut.run_all_single_board_cases(attributes={"test_env": "noXtal32k"}) # [test_env=noXtal32k]

[horw]

There are some unit test cases that use multiple groups and arguments to filter test cases, for example: [heap][mem_prot] and [test_env=noXtal32k]. So, I have added these options.

some comments regarding api, overall the code LGTM.

[hfudev]

LGTM!

[hfudev]

you're not checking the debug level in the test case, maybe remove the log cli level here?

[horw]

yes, sure
