DISABLED_FOR_TARGETS macros are used

Partly revert "ci: disable unavailable tests for esp32s2beta"

This partly reverts commit 76a3a5fb48.

Partly revert "ci: disable UTs for esp32s2beta without runners"

This partly reverts commit eb158e9a22.

Partly revert "fix unit test and examples for s2beta"

This partly reverts commit 9baa7826be.

Partly revert "efuse: Add support for esp32s2beta"
