[SYCL][ABI-Break] Drop legacy overload of queue::mem_advice

[AlexeySachkov]

We made a mistake several years ago by introducing pi_mem_advice argument into a public interface in #1239.

This mistake was caught a year later and addressed in #4100, but unfortunately instead of removing this incorrect overload, it was only deprecated. The deprecation wasn't done quite correctly, because this method is not deprecated in SYCL 2020 - it doesn't exists in SYCL 2020.

This PR removes the method completely, even though our messaging was wrong. The assumption is that there are no actual users who went and used undocumented non-public pi_mem_advice in their codebases.

This is patch is essentially a by-product of #14145 and it is done to simplify that change, i.e. PI plugins removal should not be ABI-breaking by itself, we just need to cleanup some of our exported symbols.

[AlexeySachkov]

Note for reviewers: this is one is a bit more radical, because it removes a user-facing API which we claimed to be present in the language. If we don't think that it is safe to remove it (note that #14145 also does an API-breaking change by changing pi_mem_advice argument to something from UR), then we should at least update the deprecation message saying that it is just deprecated and not deprecated in SYCL 2020 specifically.

I assume that this has nothing to do with my changes, but more of a sporadic hiccup of the OS

The only form that was ever meant to exist was the one that took an int.
