Auto merge of #12492 - bjorn3:proc_macro_abi_1_63, r=lnicola
feat: Add proc macro ABI for rustc 1.63
Fixes https://github.com/rust-lang/rust-analyzer/issues/12489
This bumps the MSRV to 1.61 due to usage of function pointers and `impl Trait` in const functions.
<details>
<summary>Diff from upstream proc_macro as of rust-lang/rust@e45d9973b2 (misses lib.rs as it got renamed to mod.rs)</summary>
