feat: improve Relocation & Utilities

[shad0wshayd3]

changes:

• add second template arg to applicable Relocation::write_ funcs for address offset
• remove AllocTrampoline from stl::write_* funcs, this is bad practice
• normalize stl::write_* support for structs with std::uintptr_t, REL::ID, REL::Offset, REL::Relocation<std::uintptr_t> static address members

I was hoping the stl stuff would be deprioritized in favor of just adding it to Relocation (where applicable)

[shad0wshayd3]

So I agree, but I don't think it would be applicable in this case. The write_* helpers aren't really related to REL::Relocation so much as they can accept it. I suppose the functions themselves could be reloaded to live in Relocation.h or the REL namespace (or even the REX namespace), but that's kind of splitting hairs, imo.
