[GITEA] Drop sha256-simd in favor of stdlib - In Go 1.21 the crypto/sha256 [got a massive improvement](https://go.dev/doc/go1.21#crypto/sha256) by utilizing the SHA instructions for AMD64 CPUs, which sha256-simd already was doing. The performance is now on par and I think it's preferable to use the standard library rather than a package when possible. ``` cpu: AMD Ryzen 5 3600X 6-Core Processor │ simd.txt │ go.txt │ │ sec/op │ sec/op vs base │ Hash/8Bytes-12 63.25n ± 1% 73.38n ± 1% +16.02% (p=0.002 n=6) Hash/64Bytes-12 98.73n ± 1% 105.30n ± 1% +6.65% (p=0.002 n=6) Hash/1K-12 567.2n ± 1% 572.8n ± 1% +0.99% (p=0.002 n=6) Hash/8K-12 4.062µ ± 1% 4.062µ ± 1% ~ (p=0.396 n=6) Hash/1M-12 512.1µ ± 0% 510.6µ ± 1% ~ (p=0.485 n=6) Hash/5M-12 2.556m ± 1% 2.564m ± 0% ~ (p=0.093 n=6) Hash/10M-12 5.112m ± 0% 5.127m ± 0% ~ (p=0.093 n=6) geomean 13.82µ 14.27µ +3.28% │ simd.txt │ go.txt │ │ B/s │ B/s vs base │ Hash/8Bytes-12 120.6Mi ± 1% 104.0Mi ± 1% -13.81% (p=0.002 n=6) Hash/64Bytes-12 618.2Mi ± 1% 579.8Mi ± 1% -6.22% (p=0.002 n=6) Hash/1K-12 1.682Gi ± 1% 1.665Gi ± 1% -0.98% (p=0.002 n=6) Hash/8K-12 1.878Gi ± 1% 1.878Gi ± 1% ~ (p=0.310 n=6) Hash/1M-12 1.907Gi ± 0% 1.913Gi ± 1% ~ (p=0.485 n=6) Hash/5M-12 1.911Gi ± 1% 1.904Gi ± 0% ~ (p=0.093 n=6) Hash/10M-12 1.910Gi ± 0% 1.905Gi ± 0% ~ (p=0.093 n=6) geomean 1.066Gi 1.032Gi -3.18% ``` (cherry picked from commit abd94ff5b59c86e793fd9bf12187ea6cfd1f3fa1) (cherry picked from commit 15e81637abf70576a564cf9eecaa9640228afb5b) Conflicts: go.mod https://codeberg.org/forgejo/forgejo/pulls/1581 (cherry picked from commit 5caea2d75aeac78fb306f58a3cf7809d5b70c7f2) (cherry picked from commit 08da542cce2c1571cedd4183268a903ab581d2e3) (cherry picked from commit d71a8cc9fb816a3b6562a661286f1d3961821b67) (cherry picked from commit 63c9fc2bee5b71e6ce3898bbf9b9bce827705acc) (cherry picked from commit e1db85d48a2de7cff0d438aac81023c4b50cdae4) (cherry picked from commit 5e86a5d2d13319c09199a35a4c0568389b03a2a2)
