3.09.00 Release

• eastl::any fix to correctly decay reference types.
• eastl::fixed_hash_map/eastl::fixed_hash_multimap fixes when a user requests to clear the bucket array hashtable rehashing was disabled with a default bucket count of 1. The behaviour now for fixed_hash_map (and fixed_hash_multimap) is the clear buckets request resets the containter to use the SBO and the default bucket count.
• Added 'eastl::is_literal_type_v' type trait.
• Added 'eastl::is_convertible_v' type trait.
• eastl::string SSO capacity is now optimal
  • HeapLayout now uses 1 pointer and 2 size_t instead of 3 pointers
  • SSO rework to now use the maximum number of bytes possible, 23 bytes of SSO on 64bit, was 14 bytes before
  • set_capacity() will now shrink to SSO if the new capacity is within SSO limits
  • shrink_to_fit() implemented
  • basic_string(const basic_string&, const Allocator&) constructor implemented
  • substr(), left(), right() now properly return a basic_string with a default constructed allocator
    when inserting yourself into yourself reduced allocations from 1 to 0 or 1.
  • is_sso() function implemented that returns true if the current string is an SSO string
  • natvis updated
• eastl::fixed_substring && eastl::fixed_string updated due to eastl::string changes
• eastl::vector::emplace_back() now returns a reference to the emplaced element
• eastl::variant::operator=(T) conversion assignment operator fixed an issue due to a incorrect conjunction expression that caused the operator to be removed via SFINAE.
• eastl::intrusive_ptr now supports move semantics.
• eastl::is_trivially_copyable fixes to use the proper compiler intrinsics.
• eastl::deque::shrink_to_fit() implemented.
