Fixes https://github.com/denoland/deno/issues/28206.
Basically if you execute a script with `node:vm`, this produces a
"script" with the file name `evalmachine.<anonymous>`, which ends up
producing coverage like
```json
{
"scriptId": "319",
"url": "evalmachine.<anonymous>",
"functions": [
{
"functionName": "",
"ranges": [{ "startOffset": 0, "endOffset": 18, "count": 1 }],
"isBlockCoverage": true
}
]
}
```
We assume that the `url` field here (the specifier of the script) is a
valid URL, and so we error out when processing that coverage.
There are two potential fixes: either don't write the coverage files for
those scripts, or ignore the errors when we process the data. I went
with the former here.
This PR removes the use of the custom `utc_now` function in favor of the
`chrono` implementation. It resolves #22864.

This PR directly addresses the issue raised in #23282 where Deno panics
if `deno coverage` is called with `--include` regex that returns no
matches.
I've opted not to change the return value of `collect_summary` for
simplicity and return an empty `HashMap` instead
1. Generally we should prefer to use the `log` crate.
2. I very often accidentally commit `eprintln`s.
When we should use `println` or `eprintln`, it's not too bad to be a bit
more verbose and ignore the lint rule.
