BUG/TST: timedelta-like with Index/Series/DataFrame ops
Broken off from #23308, with additional fixes for problems found along the way.


```
val = np.timedelta64(4*10**9, 'ns')
ser = pd.Series([val]) * 1.5

>>> ser % val   # <-- raises TypeError in master
0   00:00:02
dtype: timedelta64[ns] 
```

```
ri = pd.RangeIndex(1)
di = pd.DataFrame(ri)

>>> ri + df  # <-- raises TypeError in master
    0
0   0
```

```
td64 = np.timedelta64(4*10**9, 'ns')
tdnat = np.timedelta64("NaT", "D")
ser = pd.Series([0, 1, 2])

>>> ser + td64   # <-- fails to raise in master, now raises TypeError; ditto with tdnat
# ditto if for radd, sub, and rsub

>>> pd.Index(ser) + tdnat  # <-- in master returns all-NaT DatetimeIndex, now raises
# ditto for sub; reversed ops DO raise TypeError in master, but for wrong reason
>>> pd.DataFrame(ser) + tdnat # <-- in msater returns all-NaT timedelta64 DataFrame, now raises
# ditto for radd, sub, and rsub
```

```
off = pd.offsets.Minute()
ser = pd.Series([1, 2, 3])

>>> off / ser  # <--  raises TypeError in master
0   00:01:00
1   00:00:30
2  00:00:20
dtype: timedelta64[ns]
```




One more that isn't a bug in master, but where the new behavior is better:

```
off = pd.offsets.Minute()
ser = pd.Series([1, 2, 3])

# master
>>> ser * off
0        <Minute>
1   <2 * Minutes>
2   <3 * Minutes>
dtype: object

# PR
>>> ser * off
0   00:01:00
1   00:02:00
2   00:03:00
dtype: timedelta64[ns]
```
