feat: deno doc --html (#21015)

This commit adds static documentation site generate to "deno doc"
subcommand.

Example:
```
$ deno doc --html --name="My library" ./mod.ts
# outputs to ./docs/

$ deno doc --html --name="My library" --output=./documentation/ ./mod.ts ./file2.js
# outputs to ./documentation/

$ deno doc --html --name="My library" ./**/mod.ts
# generate docs for all files with "mod.ts" name
```
