[FileCheck] Implement -dump-input-context
This patch is motivated by discussions at each of:
* <https://reviews.llvm.org/D81422>
* <http://lists.llvm.org/pipermail/llvm-dev/2020-June/142369.html>
When input is dumped as specified by `-dump-input=fail`, this patch
filters the dump to show only input lines that are the starting lines
of error diagnostics plus the number of contextual lines specified
`-dump-input-context` (defaults to 5).
When `-dump-input=always`, there might be not be any errors, so all
input lines are printed, as without this patch.
Here's some sample output with `-dump-input-context=3 -vv`:
```
