Change default edition for stdlib to 2021
The existing default version of 2018 is incorrect for both rustc 1.75.0
and 1.76.0, and is a compiler error in 1.76.0 due to new syntax for c string literals, c"blah".
Also change edition for compiler_builtins and cfg-if to 2018, in accordance with lib/rustlib/src/rust/vendor/compiler_builtins/Cargo.toml and lib/rustlib/src/rust/vendor/cfg-if/Cargo.toml
There are no changes in editions between rustc 1.75.0 and 1.76.0, so this should be fine to submit for 1.75.0.
Details:
Most crates have edition = 2021, so this should be the default:
