cpu: add support for detecting RISC-V extensions
...
Add a RISCV64 variable to cpu that indicates both the presence
of RISC-V extensions and performance information about the underlying
RISC-V cores. The variable is only populated with non false values on
Linux. The detection code first attempts to use the riscv_hwprobe
syscall introduced in Linux 6.4, falling back to HWCAP if riscv_hwprobe
is not supported. The patch can detect the C, V, Zba, Zbb and Zbs
extensions. V, Zba, Zbb and Zbs can only be detected on a 6.5 kernel
or later (without backports).
Updates golang/go#61416

all: go fmt ./...

Make all our package sources use Go 1.17 gofmt format
(adding //go:build lines).
Not strictly necessary but will avoid spurious changes
as files are edited.
Part of //go:build change (#41184 ).
