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.

Implement conversion between rust_decimal::Decimal and decimal.Decimal
from Python's stdlib. The C API does not appear to be exposed on the
Python side so we need to call into it via Python.
Support compiling portable "abi3" extension modules even when
the build host Python interpreter configuration is not available
or the discovered Python interpreter version is not supported.
Maturin already implements this by building "abi3" extension wheels
with `PYO3_NO_PYTHON` environment veriable set for cargo when
an `abi3-py3*` feature is detected.
Closes#2292
Automatically generate `python3.dll` import libraries for Windows
compile targets in the build script.
Adds a new PyO3 crate feature `generate-abi3-import-lib` enabling
automatic import library generation.
Closes#2231
