[L0] Delete-type-mismatch output in asan

[fabiomestre]

While trying to run asan on a graph e2e test, I found an issue that seems to be related to the v2 version of the level-zero adapter. There is a new context class for v2 but delete is being called on the base class which causes a delete-type-mismatch error in asan. I don't think this is causing any major bugs but, technically, it is to be undefined behaviour. This is the asan output: asan_output.txt

This should be fixed after #1913 v2::context no longer inherits from the legacy context and they are completely separated.

#1913 has been merged. I'll close this, but feel free to reopen @fabiomestre if this is still happening.
