meson: Add '@EXTRA_ARGS@' to generate_test_runner arguments

[dloidolt]

Extended the argument list in meson generator for the test runner strict by adding '@EXTRA_ARGS@'. This change enables the test runner script to accept additional configuration parameters alongside '@input@' and '@output@', increasing its flexibility.

Hi @dloidolt,
Can you please give me a simple meson.build file, so that I can see how you manage to genrate the runner and do mocks from meson. Because I am abandoning meson because I had to run pre-meson script to generate mocks, so that meson would then get the file list to compile.

Hi @Letme,
Here is my meson.build file to generate the test runners: https://github.com/dloidolt/airs-compression/blob/c1b44753fb1dd701bc752a781d6f494c45235dba/test/meson.build#L41
I am currently not using mocks.
I hope this helps you.
Let me know if you need any more details.
