Simplifying allocator pack

[the-moisrex]

• [x] Standard Allocator doesn't have a Local Allocator
  • [x] Eliminate Additional Stack overhead
  • [x] Eliminate Additional Copy overhead
• [x] Sync/Async Allocators
• [x] Resources?
  • [ ] Store resources when the type_traits's has one
  • [ ] has_resource concept
• [x] #148
• [x] #228
• [ ] #156
• [ ] #153
• [ ] #79
• [x] #473
• [x] #474

Allocators I need:

• [x] Monotonic allocator: no-op de-alloc
• [x] General Sync Allocator

Allocators I don't need:

• Pool Allocators: User can provide them as the general sync allocator

Allocator Wrappers:

• [ ] Affix Allocator
• [ ] General Stat Allocator
  • [ ] Type of allocations
  • [ ] Snapshot of the contents
  • [ ] Allocated Types
  • [ ] Timeline of allocation
• [ ] Marked Stat Allocator
  • [ ] Stats for all allocations happening for each request
  • [ ] Using events

How should I implement Monotonic Allocator?

How about resources?

[the-moisrex]

I removed local allocator completely too.

I pretty much removed my whole allocator-pack system just because I forgot to add std::initializer_list there.

I totally wouldn't have done it if I knew the problem had nothing to do with allocators, but I'm happy I removed a ton of complicated allocator-related code!
