Rename the driver from uart_native_posix to uart_native_pty.
Including renaming the DTS compatible, and kconfig options, deprecating
the old ones.
And refactor the driver, generalizing it, so we can have any number of
instances.
Note that, unfortunately generalizing to N instances cannot be done
without a degree of backwards compatibility breakage: This driver was
born with all its configuration and selection of the instances based on
kconfig.
When the driver was made to use DT, it was done in a way that required
both DT and kconfig needing to manually coherently enable the 2nd UART.
This has now been fixed, which it means only DT is used to decide how
many instances are avaliable, and UART_NATIVE_POSIX_PORT_1_ENABLE is
just ignored.
Including:
* Deprecate UART_NATIVE_WAIT_PTS_READY_ENABLE: the options is always on
now as it has no practical drawbacks.
* Deprecate UART_NATIVE_POSIX_PORT_1_ENABLE: DTS intanciation defines it
being available now.
* Rename a few functions and in general shorten pseudo-tty/pseudo-
terminal to PTY instead of PTTY.

Device adapter strips all whitespace from output lines causing test
failures when matching default shell prompt "uart:~$ " with trailing
space. Update _handle_device_output to only strip line endings (\r\n)
while preserving whitespace required for prompt detection.
A testcase sample.pytest.shell.no_vt100 was added to verify prompt
matching works with CONFIG_SHELL_VT100_COLORS disabled.

Fixtures in pytest-twister-harness plugin are moved to one
file to simplify adding new fixtures in the future - no
need to add pytest_plugins entry and register asserts.
Moved also shell fixture from sample dir, because that
fixture can be reused in new tests.

Add readlines_until method to DeviceAdapter class to simplify using
adapters in tests by give user possibility to read output from device
until following conditions:
- provided regex was found
- provided number of lines was already read
- timeout was occurred

Select and place common code of three adapters (HardwareAdapter,
BinaryAdapterBase and QemuAdapter) into basic DeviceAdapter class.
Introduce new way of reading device output by run separate thread which
try to read device output and place it into internal python queue.
Thanks to this, now it is possible to create readline method for all
adapters, which can be unblock when timeout occur.
Collect all common steps which have to be done before setup device in
launch method. The same was done for teardown operations which were
placed into close method.
Additionally some protection mechanisms were introduced to prevent for
undesirable side-effects when user could try to launch to already
launched device or try to send some data to disconnected device.
iter_stdout method was replaced by two new methods: readline and
readlines. To make it possible to remove all read output from internal
buffer (queue), clear_buffer method was introduced.
Also unit tests were rewritten to work properly with current version
of adapters.
