[flang-rt] Runtime implementation of extended intrinsic function SECNDS() (#152021)
Until the compiler part is fully hooked up via
https://github.com/llvm/llvm-project/pull/151878, tested this using
`external`:
```
external secnds
real s1, s2
s1 = secnds(0.0)
print *, "Seconds from midnight:", s1
call sleep(2)
s2 = secnds(s1)
print *, "Seconds from s1", s2
print *, "Seconds from midnight:", secnds(0.0)
end
```
