Bumps base64 from 0.13.1 to 0.21.0. (#31522) 
Changes:

  marshallpierce/rust-base64@v0.13.1...v0.21.0

`base64::{encode,decode}` are now deprecated in favor of an API that
explicitly selects an `Engine`.  Migrated all calls to the new API.

ledger: Remove `clippy::wrong_self_convention` (#29916) 
Clippy does not seem to be complaining anymore.

It looks like this rule is now only applied to `as_` methods that take `&self`
or `&mut self` as the first argument:

  a9c251f11d/clippy_lints/src/methods/wrong_self_convention.rs (L14)

For `Copy` types, `to_` rule is applied only when the method takes `self` as the
first argument:

  a9c251f11d/clippy_lints/src/methods/wrong_self_convention.rs (L25)

Enforcement is here:

  a9c251f11d/clippy_lints/src/methods/wrong_self_convention.rs (L106)
