'win32call' needs to provide the last error

[elBoberido]

Required information

Operating system:
Windows

Rust version:
all version but with the GNU toolchain, e.g. stable-gnu

Cargo version:
N/A

iceoryx2 version:
main

Observed result or behaviour:
At a few places win32call is instructed to ignore the error and later on GetLastError is called in order to check whether the ignored error occurred. It seems that with the MinGW toolchain the subsequent call to system_error_code_to_errno resets the error and GetLastError return 0, which makes the error handling futile.

Expected result or behaviour:
Some way to access the last error.

Conditions where it occurred / Performed steps:
Run the win32_udp_port_to_uds_name_set_and_get_works_with_multiple_instances test on latest-gnu on Windows and see the test fail.
