adbb8bbcaf windows/mkwinsyscall: use syscall.SyscallN instead of syscall.Syscall{6,9,12,15} 
Replace syscall.Syscall6, Syscall9, Syscall12, and Syscall15 with syscall.SyscallN for Go 1.18+. This simplifies system calls by allowing the exact number of arguments needed, eliminating zero padding and reducing potential errors.

Updated TestSyscallXGeneration to TestSyscallNGeneration to verify correct SyscallN generation for different argument counts.

7143f4a4e1 windows: manually initialize NewNTUnicodeString 
The `RtlInitUnicodeString` syscall can be avoided by manually
initializing the `NTUnicodeString`.

The process is described in [WdmlibRtlInitUnicodeStringEx](https://learn.microsoft.com/en-us/windows-hardware/drivers/ddi/wdmsec/nf-wdmsec-wdmlibrtlinitunicodestringex).

The less syscalls, the better. It also makes the function faster:

cbf0eb65e7 unix: fix grep syntax to work on non-GNU greps 
CL 432835 changed two grep commands in unix/mkerrors.sh in such a way
that is incompatible with AIX's grep, which, unlike GNU grep, does not
support extended regular expressions without the -E flag. The intent of
this PR is to restore the egrep behavior by invoking grep as grep -E.
My assumption is that GNU grep is not meant to be a requirement to run
mkerrors.sh, and given that, grep -E looks like the most cross-platform
approach.

Example of current (incorrect) behavior on AIX:

bash-5.2$ printf 'SIGHUP\nSIGMAX64\nSIGTERM' | grep -v 'SIGSTKSIZE\|SIGSTKSZ\|SIGRT\|SIGMAX64'
SIGHUP
SIGMAX64
SIGTERM

Behavior before CL 432835:

bash-5.2$ printf 'SIGHUP\nSIGMAX64\nSIGTERM' | egrep -v '(SIGSTKSIZE|SIGSTKSZ|SIGRT|SIGMAX64)'
SIGHUP
SIGTERM

Behavior of proposed change:

bash-5.2$ printf 'SIGHUP\nSIGMAX64\nSIGTERM' | grep -E -v '(SIGSTKSIZE|SIGSTKSZ|SIGRT|SIGMAX64)'
SIGHUP
SIGTERM

OpenBSD's grep behaves the same as AIX for the above commands, which is
why I cast this as GNU vs. non-GNU. I haven't tested any other
implementations.

3283fc3f61 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).

a8c5219b5e unix: rename XDPUmemReg field back to Size 
When the Linux-specific XDPUmemReg struct was originally added
(CL 136695) the only field with a prefix was chunk_size,
so cgo rewrote the field to Size. Later Linux added a tx_metadata_len
field, which caused cgo to to leave the chunk_size field as Chunk_size
(CL 577975).

However, existing code, specifically gvisor, refers to the field
as Size. So go back to Size so that existing code will continue
to work.

This does unfortunately mean that people who used the struct since CL
577975 in April, 2024 will have to adapt. There doesn't seem to be a
perfect solution here. But we've had Size since September, 2018,
so let's stick with that.

914deed708 unix: add missing ETHTOOL_FLAG_ constants 
Some constants were removed in CL 600516 that included changes for the
Linux kernel 6.10.

This kernel version moved C defines to an enum ethtool_header_flags that
was not picked up by the mkall.sh script.

For enums, there is a perl script that needs to be run manually, and the
output must be added by hand to the list of constants in unix/linux/types.go.

See https://elixir.bootlin.com/linux/v6.10.3/source/include/uapi/linux/ethtool_netlink.h#L120
