Provide appropriate implementations of Tc{get,set}pgrp and export
these for use in the TestForeground* tests in exec_unix_test.go.
This avoids calling ioctl via syscall.Syscall on BSDs.

CL 520266 added pidfd_send_signal linux syscall numbers to the
syscall package for the sake of a unit test.
As pidfd_send_signal will be used from the os package, let's revert the
changes to syscall package, add the pidfd_send_signal syscall numbers
and the implementation to internal/syscall/unix, and change the above
test to use it.
Updates #51246.
For #62654.

Add PidFD support, so that if the PidFD pointer in SysProcAttr is not
nil, ForkExec (and thus all its users) obtains a pidfd from the kernel
during clone(), and writes the result (or -1, if the functionality
is not supported by the kernel) into *PidFD.
The functionality to get pidfd is implemented for both clone3 and clone.
For the latter, an extra argument to rawVforkSyscall is needed, thus the
change in asm files.
Add a trivial test case checking the obtained pidfd can be used to send
a signal to a process, using pidfd_send_signal. To test clone3 code path,
add a flag available to tests only.
Updates #51246.

Add the rawSyscallNoError wrapper function which is used for Linux
syscalls that don't return an error and convert all applicable
occurences of RawSyscall to use it instead.
