feat: add `--allow-import` flag (#25469)

This replaces `--allow-net` for import permissions and makes the
security sandbox stricter by also checking permissions for statically
analyzable imports.

By default, this has a value of
`--allow-import=deno.land:443,jsr.io:443,esm.sh:443,raw.githubusercontent.com:443,gist.githubusercontent.com:443`,
but that can be overridden by providing a different set of hosts.

Additionally, when no value is provided, import permissions are inferred
from the CLI arguments so the following works because
`fresh.deno.dev:443` will be added to the list of allowed imports:

```ts
deno run -A -r https://fresh.deno.dev
```
