tcl/target: Add Geehy APM32F0x config

Tested with APM32F030C8T using SWD transport. All flash operations,
including sector and device protection, work as expected.

Revision identifier (0x0011) is not updated due to missing documentation.

Introduce a new directory structure that contains the manufacturer for
the sake of clarity.
