* Add frozenset, and allow it cast to std::set
For the reverse direction, std::set still casts to set. This is in concordance with the behavior for sequence containers, where e.g. tuple casts to std::vector but std::vector casts to list.
Extracted from #3886.
* Rename set_base to any_set to match Python C API
since this will be part of pybind11 public API
* PR: static_cast, anyset
* Add tests for frozenset
and rename anyset methods
* Remove frozenset default ctor, add tests
Making frozenset non-default constructible means that we need to adjust pyobject_caster to not require that its value is default constructible, by initializing value to a nil handle. This also allows writing C++ functions taking anyset, and is arguably a performance improvement, since there is no need to allocate an object that will just be replaced by load.
Add some more tests, including anyset::empty, anyset::size, set::add and set::clear.

* Clear Python error state if pybind11::weakref() fails.
The weakref() constructor calls pybind11_fail() without clearing any

error state.

The original pybind11 holder supported multiple inheritance by recursively creating
type casters until it finds one for the source type, then converting each
value in turn to the next type via typeinfo->implicit_cast
The smart_holder only stored the last implicit_cast, which was incorrect.
This commit changes it to create a list of implicit_cast functions that are
appended to during the recursive type caster creation, and when the time comes
to cast to the destination type, it calls all of them in the correct order.
* Add tests demonstrating smart_holder issues with multiple inheritance
* Propagate C++ multiple inheritance markers to all children
- Makes py::multiple_inheritance only needed in base classes hidden from pybind11

* Expand string_view support to str, bytes, memoryview
1. Allows constructing a str or bytes implicitly from a string_view;
this is essentially a small shortcut allowing a caller to write
`py::bytes{sv}` rather than `py::bytes{sv.data(), sv.size()}`.
2. Allows implicit conversion *to* string_view from py::bytes -- this
saves a fair bit more as currently there is no simple way to get such
a view of the bytes without copying it (or resorting to Python API
calls).
(This is not done for `str` because when the str contains unicode we
have to allocate to a temporary and so there might not be some string
data we can properly view without owning.)
3. Allows `memoryview::from_memory` to accept a string_view. As with
the other from_memory calls, it's entirely your responsibility to
keep it alive.
This also required moving the string_view availability detection into
detail/common.h because this PR needs it in pytypes.h, which is higher
up the include chain than cast.h where it was being detected currently.
* Move string_view include to pytypes.h
* CI-testing a fix for the "ambiguous conversion" issue.
This change is known to fix the `tensorflow::tstring` issue reported under https://github.com/pybind/pybind11/pull/3521#issuecomment-985100965
TODO: Minimal reproducer for the `tensorflow::tstring` issue.
