Investigate how to skip unsupported tests with CTest

[LDong-Arm]

Description of defect

With Mbed CLI 1, unsupported tests are excluded in two ways:

• Tests under excluded directories (e.g. FEATURE_BLE for a non-BLE target) are not compiled or listed at all
• Tests under "visible" directories are listed, but during compile time the test source performs macros checks and raises #error [NOT_SUPPORT], which Mbed CLI 1 parses

Parsing an error message is not ideal, so we may use CMake to check feature availability instead. This task is to investigate how to do this.
