This allows us to drop the `//go:generate` and use of the github.com/mjibson/esc
utility.
worth noting that Go's native "embed" does not compress files. We could compress
these files as part of a build / validate step (which would add some complexity
when updating these files) if this is a concern, but not sure if the additional
complexity is warranted.

When creating and updating services, we need to avoid unneeded service churn.
The interaction of separate lists to "add" and "drop" capabilities, a special
("ALL") capability, as well as a "relaxed" format for accepted capabilities
(case-insensitive, `CAP_` prefix optional) make this rather involved.
This patch updates how we handle `--cap-add` / `--cap-drop` when _creating_ as
well as _updating_, with the following rules/assumptions applied:
- both existing (service spec) and new (values passed through flags or in
the compose-file) are normalized and de-duplicated before use.
- the special "ALL" capability is equivalent to "all capabilities" and taken
into account when normalizing capabilities. Combining "ALL" capabilities
and other capabilities is therefore equivalent to just specifying "ALL".
- adding capabilities takes precedence over dropping, which means that if
a capability is both set to be "dropped" and to be "added", it is removed
from the list to "drop".
- the final lists should be sorted and normalized to reduce service churn
- no validation of capabilities is handled by the client. Validation is
delegated to the daemon/server.
When deploying a service using a docker-compose file, the docker-compose file
is *mostly* handled as being "declarative". However, many of the issues outlined
above also apply to compose-files, so similar handling is applied to compose
files as well to prevent service churn.

Both libaries provide similar functionality. We're currently using
Google Shlex in more places, so prefering that one for now, but we
could decide to switch to mattn/go-shellwords in future if that
library is considered better (it looks to be more actively maintained,
but that may be related to it providing "more features").

This is not currently used by the CLI, but can be used by
docker compose to bring parity on this feature with the
compose v2.4 schema.

67ebcd6dcf added an exception for
the "host-gateway" magic value to the validation rules, but didn't
add thise value to any of the tests.
This patch adds the magic value to tests, to verify the validation
is skipped for this magic value.
Note that validation on the client side is "optional" and mostly
done to provide a more user-friendly error message for regular
values (IP-addresses).

Before this change, this would cause a panic:
docker run -it --rm -v 1:/1 alpine
panic: runtime error: index out of range
goroutine 1 [running]:
github.com/docker/cli/cli/compose/loader.isFilePath(0xc42027e058, 0x1, 0x557dcb978c20)
...
After this change, a correct error is returned:
docker run -it --rm -v 1:/1 alpine
docker: Error response from daemon: create 1: volume name is too short, names should be at least two alphanumeric characters.

Added transforms for when merging compose overrides to preserve the
functionality that was broken by bumping mergo to v1.3.8
This includes:
- Special transform for ulimits so single overrides both soft/hard and
the reverse
- Special transform for service network configs so the override replaces
all aliases

When deploying a stack using a relative path as bind-mount
source in the compose file, the CLI converts the relative
path to an absolute path, relative to the location of the
docker-compose file.
This causes a problem when deploying a stack that uses
an absolute Windows path, because a non-Windows client will
fail to detect that the path (e.g. `C:\somedir`) is an absolute
path (and not a relative directory named `C:\`).
The existing code did already take Windows clients deploying
a Linux stack into account (by checking if the path had a leading
slash). This patch adds the reverse, and adds detection for Windows
absolute paths on non-Windows clients.
The code used to detect Windows absolute paths is copied from the
Golang filepath package;
