issues with some SVG rasterizers.

This patch adds a new `alacritty msg get-config` subcommand which can
retrieve the current config from any Alacritty window using the IPC
socket.

The command will always print the full configuration file in JSON,
without the ability to filter which values are returned, leaning on
tools like `jq` instead of adding this complexity to Alacritty.

Contrary to deserialization, this relies heavily on the default
serialization implementations to reduce the necessary changes. Key and
Mouse bindings are omitted entirely since their structure is very
complex and they tend to just bloat the message size without having an
obvious usecase.

This patch adds Vi's semantic search and paragraph motion.

The semantic search uses either the selection or the semantic word under
the cursor and jumps to the next match in the desired direction.

Paragraph motion jumps to just above or below the current paragraph.

Closes #7961.

This adds the `\` character to the list of characters which will
terminate matches in Alacritty's default hint for URL recognition.
