This fixes an issue where a scrolling region that does not start at the
top of the screen would still rotate lines into history when scrolling
the content "upwards".

This patch adds a new CLI parameter to the `create-window` subcommand,
matching the existing `--option` parameter when creating a new Alacritty
instance.

This parameter allows setting up the initial window configuration from
the CLI without having to call `alacritty msg config`, making sure that
all options are set appropriately right from the start.

Closes #6238.

There's no need to force alacritty's user configuration on
other users of the crate, thus provide the options actually used
by alacritty_terminal itself.

The special character `;` can be not URL-encoded, thus it'll add
extra parameter in the payload. Handle it joining extra parameters
with the `;` as a separator.

When the erase in line escape sequence with a parameter of 0 (right) is
passed while the wrapline flag is already set, it will no longer clear
the last column and instead ignore the operation.

The behavior of `\e[1K` and `\e[2K` is unchanged and both will clear the
entire first line without clearing the wrapline flag.

Fixes #6215.
