When the test runs with code coverage, make sure the coverage dump
completes its output under pytest execution before the test debug
session ends in both cases: for Zephyr gdbstub feature and for
Qemu internal GDB stub.
Add few more test operations with breakpoints.

Add `gdb_target_remote` test parameter for GDB `target remote`
command instead of its hardcoded value to allow different types
of gdbstub serial interfaces as well as different TCP ports in
gdbstub test suites possibly run in parallel on the same host.
Move all GDB log configuration parameters from GDB script to
the fixture code.

Gdbstub test improvements: using pytest fixtures, parametrization, and
expected pattern matching on outputs from GDB and the test application.
