Summary:
Added `fbcode` symlinks for `platform010` & `platform010-aarch64` and addressed the following fixes:
* Account for stabilized [`#![feature(backtrace)]`](https://github.com/rust-lang/rust/pull/99573) and [`#![feature(generic_associated_types)]`](https://github.com/rust-lang/rust/pull/99573)
* Account for removal of [`#![feature(result_into_ok_or_err)]`](https://github.com/rust-lang/rust/pull/100604)
* Account for migration of [`std::io::ReadBuf` to `std::io::BorrowBuf|BorrowCursor`](https://github.com/rust-lang/rust/pull/97015)
* Account for [`Error` trait move into core](https://github.com/rust-lang/rust/pull/99917)
* Account for `#[warn(non_camel_case_types)]`
* Various function signature, lifetime requirement changes and lint fixes
