3211: Enable v2 resolver on the workspace to enable dropping PYO3_CI workaround r=davidhewitt a=adamreichold

3210: Drop the xtask helper as it is superseded by Nox. r=davidhewitt a=adamreichold
While the xtask code base is better engineered than our slightly messy Nox manifest, all functionality is available via Nox including some that is not available via xtask. Finally, only the Nox sessions are used in the CI by now so that xtask does not see regular automated usage.

3203: support ordering magic methods for `#[pyclass]` r=adamreichold a=davidhewitt
Closes#2089
This adds `__lt__`, `__le__`, `__eq__`, `__ne__`, `__gt__`, and `__ge__` as per the Python implementations of what we call `__richcmp__`.
There's a UI test confirming that the user cannot implement split forms and `__richcmp__` simultaneously.
There's also a benchmark comparing implementing these split methods against using `__richcmp__`. I couldn't see a meaningful performance difference, so I'm tempted to deprecate `__richcmp__`, given that's not a magic method which exists in Python. Potentially we can provide options such as the opt-in `#[pyclass(eq, ord)]` to avoid boilerplate for people who don't want to implement six different methods.

3208: bump msrv to 1.56 r=davidhewitt a=davidhewitt
The MSRV changes from #3204, plus a commit which should hopefully make CI pass.
With luck this is mergeable and resolves CI pain while we decide what to do about the Python version.

3200: RFC: remove copyright headers from source files r=davidhewitt a=davidhewitt
As part of our relicensing effort - I've observed that over time we haven't applied COPYRIGHT headers consistently to source files.
I've seen different organisations take different approaches to this. I note that for [`rust-lang/rust`, headers only exist where code has been moved inside the Rust repo without relicensing](https://github.com/search?q=repo%3Arust-lang%2Frust+copyright+language%3ARust&type=code&l=Rust).
For PyO3, I suggest we follow this and remove COPYRIGHT headers from source. We may wish to consider attributing to `rust-cpython` as the original project from which PyO3 was forked, possibly in the License section of the readme?

3185: Fix `abi3` conversion of `__complex__` classes r=adamreichold a=jakelishman
Python classes that were not `complex` but implemented the `__complex__` magic would have that method called via `PyComplex_AsCComplex` when running against the full API, but the limited-API version `PyComplex_RealAsDouble` does not attempt this conversion. If the input object is not already complex, we can call the magic before proceeding.
Happy to modify if I've made a mess of testing strategy - I'm not sure I've managed to do it in the same style as other tests.
Fix#3164.

3199: update PR template to detail state of licensing r=davidhewitt a=davidhewitt
Adds detail about #3108 to the README and the PR template.
`@DataTriny` - I thought that adding this would help encourage new contributors to be aware of the licensing terms and also that they would need to explicitly accept the future license.

magic would have that method called via `PyComplex_AsCComplex` when

`PyAny::lookup_special` is an approximate equivalent to the CPython
internal `_PyObject_LookupSpecial`, which is used to resolve lookups of
"magic" methods. These are only looked up from the type, and skip the
instance dictionary during the lookup. Despite this, they are still
required to resolve the descriptor protocol.
Many magic methods have slots on the `PyTypeObject` or respective
subobjects, but these are not necessarily available when targeting the
limited API or PyPy. In these cases, the requisite logic can be worked
around using safe but likely slower APIs.

As per #3154 I think we're ready to push 0.19.
I'll put this live on Tuesday evening unless I hear a reason to postpone.
