[DeviceAsan] Symbolizer may destruct before SanitizerInterceptor

[yingcong-wu]

We may try to use symbolizer in the destructor of SanitizerInterceptor, but since we are using a static Symbolizer, we cannot control it's destruction order and it can be destructed before SanitizerInterceptor layer. This patch tries to manually let the Symboilzer destruct at the very end of the exit process.

Hi @pbalcer , we have another internal discussion and we still think having a symbolizer within the context is strange and we don't want that. Instead, we will construct a symbolizer each time we try to use it. Symbolization happened in the error reporting stage and we don't think performance is a problem at that stage.

By doing so we won't have the symbolizer in the context and won't have the destruction order problem too.

Sure, makes sense. Another option could be using the AtomicSingleton type - https://github.com/oneapi-src/unified-runtime/blob/main/source/common/ur_util.hpp#L427, but that might be an overkill.
