all: update vendored golang.org/x dependencies for Go 1.19 release

The Go 1.19 code freeze has recently started. This is a time to update
all golang.org/x/... module versions that contribute packages to the
std and cmd modules in the standard library to latest master versions.

This CL updates the rest of the modules with x/build/cmd/updatestd.

For #36905.

// the type name from the receiver, and only have to look over the type's
// methods to find the method index.
//
// Methods on generic types require special consideration, however. Consider
// the following package:
//
// L1: type S[T any] struct{}
// L2: func (recv S[A]) Foo() { recv.Bar() }
// L3: func (recv S[B]) Bar() { }
// L4: type Alias = S[int]
// L5: func _[T any]() { var s S[int]; s.Foo() }
//
// The receivers of methods on generic types are instantiations. L2 and L3
// instantiate S with the type-parameters A and B, which are scoped to the
// respective methods. L4 and L5 each instantiate S with int. Each of these
// instantiations has its own method set, full of methods (and thus objects)
// with receivers whose types are the respective instantiations. In other
// words, we have
//
// S[A].Foo, S[A].Bar
// S[B].Foo, S[B].Bar
// S[int].Foo, S[int].Bar
//
// We may thus be trying to produce object paths for any of these objects.
//
// S[A].Foo and S[B].Bar are the origin methods, and their paths are S.Foo
// and S.Bar, which are the paths that this function naturally produces.
//
// S[A].Bar, S[B].Foo, and both methods on S[int] are instantiations that
// don't correspond to the origin methods. For S[int], this is significant.
// The most precise object path for S[int].Foo, for example, is Alias.Foo,
// not S.Foo. Our function, however, would produce S.Foo, which would
// resolve to a different object.
//
// For S[A].Bar and S[B].Foo it could be argued that S.Bar and S.Foo are
// still the correct paths, since only the origin methods have meaningful
// paths. But this is likely only true for trivial cases and has edge cases.
// Since this function is only an optimization, we err on the side of giving
