Auto merge of #91970 - nrc:provide-any, r=scottmcm
Add the Provider api to core::any This is an implementation of [RFC 3192](https://github.com/rust-lang/rfcs/pull/3192) ~~(which is yet to be merged, thus why this is a draft PR)~~. It adds an API for type-driven requests and provision of data from trait objects. A primary use case is for the `Error` trait, though that is not implemented in this PR. The only major difference to the RFC is that the functionality is added to the `any` module, rather than being in a sibling `provide_any` module (as discussed in the RFC thread). ~~Still todo: improve documentation on items, including adding examples.~~ cc `@yaahc`
