tests: enable stack trace tests for x86_64-selfhosted
Allows the stack trace tests to be additionally compiled and run with `.use_llvm = false, .use_lld = false` depending on the host target. This is currently enabled for x86_64 targets emitting ELF. Self-hosted backends emit slightly different DWARF info to the LLVM backend, so the checking logic (and the tests themselves) had to be tweaked slightly to support both backends at once.
