lib/sha256: Remove it (#9643) 
### Purpose

Remove the `lib/sha256` package, because it's no longer necessary. Go's
standard library now has the same performance and is on par with
`sha256-simd` since [Since Go
1.21](1a64574f42).
Therefore using `sha256-simd` has no benefits anymore.

ARM already has optimized sha256 assembly code since
7b8a7f8272,
`sha256-simd` published their results before that optimized assembly was
implemented,
f941fedda8.
The assembly looks very similar and the benchmarks in the Go commit
match that of `sha256-simd`.

This patch removes all of the related code of `lib/sha256` and makes
`crypto/sha256` the 'default'.

Benchmark of `sha256-simd` and `crypto/sha256`:

all: Use Linux container CPU quota (fixes #9357, fixes #9435) (#9436) 
Go is not cgroup aware and by default will set GOMAXPROCS to the number
of available threads, regardless of whether it is within the allocated
quota. This behaviour causes high amount of CPU throttling and degraded
application performance.
