3029: use dynamic trampoline for all getters and setters r=adamreichold a=davidhewitt
This is an extension to the "trampoline" changes made in #2705 to re-use a single trampoline for all `#[getter]`s (and similar for all `#[setters]`). It works by setting the currently-unused `closure` member of the `ffi::PyGetSetDef` structure to point at a new `struct GetSetDefClosure` which contains function pointers to the `getter` / `setter` implementations.
A universal trampoline for all `getter`, for example, then works by reading the actual getter implementation out of the `GetSetDefClosure`.
Advantages of doing this:
- Very minimal simplification to the macro code / generated code size. It made a 4.4% reduction to `test_getter_setter` generated size, which is an exaggerated result as most code will probably have lots of bulk that isn't just the macro code.
Disadvantages:
- Additional level of complexity in the `getter` and `setter` trampolines and accompanying code.
- To keep the `GetSetDefClosure` objects alive, I've added them to the static `LazyTypeObject` inner.
- Very slight performance overhead at runtime (shouldn't be more than an additional pointer read). It's so slight I couldn't measure it.
Overall I'm happy to either merge or close this based on what reviewers think!

2981: Remove 0.17 deprecations r=adamreichold,davidhewitt a=davidhewitt
Since #2980 starts a breaking change for 0.19, let's also clean up all 0.17's deprecations.
I've removed `Python::acquire_gil` in its own commit, as that was a reasonably chunky removal.

3004: Unwrap dynamic error types when inner is simple `PyErr` r=davidhewitt,adamreichold,mejrs a=BlueGlassBlock
This is the first part of suggested improvements in #2998.
This change will make bubbled `PyErr` wrapped in `eyre::Report` / `anyhow::Error` bubble up unchanged, instead of being wrapped in a `PyRuntimeError`.

3141: Add BaseExceptionGroup for Python >= 3.11 r=adamreichold a=adriangb
Not sure if this is totally off base, but it looks like it may be this easy to add support for ExceptionGroup?

2980: support `text_signature` on `#[new]` r=adamreichold a=davidhewitt
Closes#2866
This is a breaking change for 0.19.0, because it starts autogenerating `text_signature` for `#[new]`. This could affect runtime behaviour if the user is relying on the class docs at runtime for some reason.
Guide & tests all updated accordingly.
`#[pyclass(text_signature = "...")]` is deprecated by this PR, however if it's set, it will be used in preference to `#[new]`.
(The signature / `text_signature` from `#[new]` will simply be ignored in this case. I figure that when users fix their deprecation warnings by removing `#[pyclass(text_signature = "...")]` then the `#[new]` signatures will start flowing properly, and this is good enough.)

3016: implement Decimal to rust_decimal conversions r=adamreichold a=cardoe
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.
Implements #2774
