___tracy_alloc_*
take pointer-size pairs
This enables better bindings in languages that do not have 0-terminated strings for source/function name. It does not introduce any additional overhead in languages that do use 0-terminated strings, either, but it _is_ a breaking API change. Fixes https://github.com/wolfpld/tracy/issues/53
