Remove extra defines from `test/support/test_config.h` file

[SergeyKopienko]

In this PR we remove extra defines from test/support/test_config.h which mark broken test cases in the tests of std::complex.

Motivation described here: https://github.com/oneapi-src/oneDPL/pull/1566#discussion_r1592663793

I know this is now a draft, but I just want to preserve the state of my review: I've checked that the removed macros are properly replaced with their new consolidated replacement.

We will need to follow up on the following tests to see if we have added any new failures which need to be addressed by fixing the #ifndef bug which reenables some unintentionally skipped assertions.

Affected tests: acosh.pass asin.pass atan.pass cosh.pass pow_complex_complex.pass pow_complex_scalar.pass pow_scalar_complex.pass sin.pass norm1.pass polar.pass
