When changing https://chrisdown.name over from Pygments to Rouge, one
quite noticeable change was that `{% highlight c %}` blocks lost the
delineation between #include statements and the actual include, with
them all now just being stylised as a comment.

This patch brings back Comment::PreprocFile support for C-like
languages, as it was with Pygments.

Tested locally by rebuilding chrisdown.name with a gem from this commit,
and seeing that the Comment::PreprocFile highlighting reappeared.

This commit supports quoted keys in standard key/value pair as well as
ones inside inline table.

HCL is used in [Terraform which uses the `.tf` file
extension](https://www.nomadproject.io/docs/commands/job/run#examples)
but it is already handled by the [terraform
lexer](https://github.com/rouge-ruby/rouge/blob/master/lib/rouge/lexers/terraform.rb).
But HCL is also used by other Hashicorp tools like:
 * [Packer which uses the `.pkr.hcl`
   extension](https://www.nomadproject.io/docs/commands/job/run#examples)
 * [Vault which uses the `.hcl`
   extension](https://www.vaultproject.io/docs/commands/server#command-options)
 * [Consul which uses the `.hcl`
   extension](https://www.consul.io/docs/agent/options#configuration)
 * [Waypoint which uses the `waypoint.hcl`
   file](https://www.waypointproject.io/docs/waypoint-hcl#project-configuration-waypoint-hcl)
 * [Nomad which uses the `.nomad`
   extension](https://www.nomadproject.io/docs/commands/job/run#examples)
   but also [Nomad Packs which uses the `.hcl`
   extension](https://learn.hashicorp.com/tutorials/nomad/nomad-pack-writing-packs#add-a-new-pack)

(in fact the [list of HCL
Schemas](https://learn.hashicorp.com/tutorials/nomad/nomad-pack-writing-packs#add-a-new-pack)
seems to be the most comprehensive list of HCL implementations)
