Add synchronization using semaphores for the UART ISR tx/rx
tests, instead of relying on a single k_yield() call to
ensure all UART ISR work can be completed before validating
the result.

Most tests define a buffer for UART data on the stack,
including the tests testing UART IRQ. Move buffers to
static memory, within the test fixture, which can then
be passed as the user_data to the UART IRQ callback.

Twister now supports using YAML lists for all fields that were written
as space-separated lists. Used twister_to_list.py script. Some artifacts
on string length are due to how ruamel dumps content.
