chore: upgrade base64-simd to 0.8.0 (#17463)

This PR upgrades the `base64-simd` dependency of `deno_web`.

base64-simd v0.8 supports `forgiving_decode` in ["copy"
mode](https://docs.rs/base64-simd/0.8.0/base64_simd/fn.forgiving_decode.html),
["inplace"
mode](https://docs.rs/base64-simd/0.8.0/base64_simd/fn.forgiving_decode_inplace.html)
or ["alloc"
mode](https://docs.rs/base64-simd/0.8.0/base64_simd/fn.forgiving_decode_to_vec.html).
When #17159 resolves, they can be used to reduce unnecessary allocations
and copies.

base64-simd v0.8 also supports AArch64 SIMD out of box.
