Replace declspec(import/export) approach with method consolidation:
- Remove detail::static_fn infrastructure
- Revert fn to simple static method member (not via MAKE_STATICS)
- In augment_methods(), group methods by type_id and collect
  overriders from all module copies into canonical method
- Build dispatch tables once per unique method, not once per copy

This avoids intrusive list manipulation during initialization while
enabling correct dispatch table construction with shared method state
across DLL boundaries.

- Resolve deferred type IDs before consolidation (deferred_static_rtti)
- Update test_custom_rtti to assign unique IDs to non-polymorphic types
  via non_polymorphic_static_type<T>() function-local counter, so method
  tag classes don't collapse to a single sentinel and trigger spurious
  ambiguous dispatch
- Remove get_fn test from dynamic_loading: each module now has its own
  fn instance, so address equality no longer holds (the state is
  synchronized via consolidation at initialize time instead)

All 77 tests pass.

- Add `meet` multi-method to test_dynamic_loading so the test exercises
  multiple methods and non-zero slots/strides — previously the test
  accidentally passed because the lone `speak` method got slot 0
  (matching zero-initialized arrays in non-local module fns)
- Rename `canonical_methods` → `local_methods` in augment_methods: the
  selected method_info isn't canonical in any global sense, it's just
  the one that happens to live in the module performing initialize()
- After dispatch table build, copy slots_strides values from each
  local method_info to all other module copies. Each module's `fn`
  has its own slots_strides[] array and dispatch reads it directly,
  so every copy must hold the same values.

Iterating methods directly and skipping the self pointer is clearer than
building a side map keyed by type_index.

Revert from signed int back to std::size_t. To distinguish polymorphic
from non-polymorphic types, set the high bit (1 << (sizeof(size_t)*8-1))
in the non_polymorphic_static_type counter values. Polymorphic Animal/
Dog/Cat keep small positive values 1/2/3; method tag classes get values
like 0x800...001, 0x800...002 — comfortably outside the 1..3 range used
by type_name. Avoids the size mismatch warnings (C4312) that b2's W4/WX
flags treat as errors on the int->const-void* reinterpret_cast path.

Policy state moved into registry_state, so stderr_output::os is now a deprecated alias and stream() returns the registry-backed stream. The library's own diagnostics still wrote to os, which broke warnings-as-errors builds (e.g. b2 with /WX). Route them through stream() and give the test's capture_output policy a stream() accessor.

boost::dll resolves the relative library name against the working directory. Without WORKING_DIRECTORY, ctest ran the test from the binary tree where a stale boost_openmethod-shared.dll could be picked up, failing at load with ERROR_PROC_NOT_FOUND. Point it at $<TARGET_FILE_DIR:boost_openmethod-dynamic>, where the freshly-built DLL sits co-located with the exe.

registry_state::policy<P>() uses the type-indexed std::get<T>(tuple),
declared in <tuple>. Newer toolchains pulled the header in transitively,
but gcc-12's libstdc++ did not, so only the std::pair overloads of
std::get were visible and the call failed to compile. Include <tuple>
explicitly in the headers that use std::tuple/std::get.
