Feature - support build with Go 1.21

[yorickdowne]

Rationale

Go 1.21 is the current stable implementation, and will be the lowest supported version once Go 1.22 releases in Q1 2024.

Implementation

The quic-go dependency would need to be updated from 0.33.0 to something more recent that supports Go 1.21, e.g. 0.37.3

Error message when building with Go 1.21 currently:

21.00 # github.com/quic-go/quic-go/internal/qtls
21.00 /go/pkg/mod/github.com/quic-go/quic-go@v0.33.0/internal/qtls/go121.go:5:13: cannot use "The version of quic-go you're using can't be built on Go 1.21 yet. For more details, please see https://github.com/quic-go/quic-go/wiki/quic-go-and-Go-versions." (untyped string constant "The version of quic-go you're using can't be built on Go 1.21 yet. F...) as int value in variable declaration

quic-go from 0.37 on no longer requires its own TLS code, which means it should survive updates to the Go compiler far more easily:

"With the upcoming Go 1.21 release, we're now able to rely on the Go standard library's TLS implementation's QUIC support."

Note that the dependency graph is something like this:

bsc -> prysm -> libp2p -> quic-go

libp2p is compatible w/ Go 1.21 (and quic-go) ; so from the PoV of bsc prysm needs to be updated

[brilliant-lx]

the latest prysm v4.1.0 still not support golang v1.21 yet, we have the dependency right now.
BSC can upgrade to v1.21, once prysm supports v1.21,

[yorickdowne]

Prysm builds fine with golang 1.21 on my machine, even as their official builds aren’t using it yet.

You have about 2 months before Go 1.20 is no longer supported by its maintainers. Prysm v4.1.1 builds with Go 1.21 for me.

We can support it in next release as long as Prysm supports Go 1.21 now.

I build prysm with the newest code in develop ,but still report quic-go issue

to solve this problem, should change go-libp2p version to v0.30.0 from v0.26.2,
because go-libp2p v0.30.0 is the first version include quic-go 0.37.0
Unfortunately, v0.30.0 is not compatible with v0.26.2, so I add a Feature Request to prysm .
once prysm support go v1.21, bsc client will support it

[buddh0]

develop branch of prysm can build with go v1.21 now , but not tagged
once a tag released, bsc will support it

have supported in latest develop
