twister: a lot of NONE test case statuses

[golowanow]

Describe the bug
Twister don't set TestCase result status (remains NONE) in two execution modes:

• a test suite has testcase.yaml with an integration platform which is not available to run - an example observed on CI
• --cmake-only.

To Reproduce
./scripts/twister -j 1 -vv -ll DEBUG -p sam_e70_xplained/same70q21 -T tests/subsys/dsp/basicmath
./scripts/twister -j 1 -vv -ll DEBUG -p native_sim -T tests/kernel/sleep --cmake-only

Expected behavior
TestCases have correct status, no errors.

Impact

• incorrect (missed) TestCase result statuses,
• flood of ERRORs in Twister log.
