This adds the ability to source additional local build definition files when
sourcing Bake files via a remote url.
Prefixing a file with 'cwd://' will source a bake file on the local
machine, instead of the remote location.
Local files will be read/have precedence before remote files.
Usage:
```
docker buildx bake https://github.com/example/upstream.git --file cwd://docker-bake.override.hcl --print
```
This will source a default file from the example/upstream repository,
and also source a build definition from the local machine.
Also moves remote and local files reading logic to a func

ReadLocalFiles should allow passing the stdin file as an argument, which
allows us to read from dockerCli.Stdin() to be consistent with other
commands in the same package.

Previously, when directly modifying the args map when reading targets,
we could end up in a scenario where bake tests that compare arg maps
would fail if SOURCE_DATE_EPOCH was set in the environment.
This patch prevents this failure by setting the SOURCE_DATE_EPOCH at the
command level (which isn't injected into tests as well), ensuring that
we test correctly even when SOURCE_DATE_EPOCH is set in the environment.

We can perform all attestation processing, handling how the sbom and
provenance arguments interact on the client, while applying defaults on
the server.
Additionally, this allows us to start pulling fields out of CommonOpts.

The NewPrinter function is mostly borrowed from buildkit. However, at
some point, it seems that the implementations drifted.
This patch updates buildx to be more similar in behavior to it's
buildkit counterpart, specifically, it will explicitly fail if a TTY
output is requested using "--progress=tty", but the output is not
available.
To gracefully fallback to plain progress in this scenario,
"--progress=plain" is required.

Groups that contained other groups were not recursively resolved by
ReadTargets, which prevented output from --print from being useable as a
self-contained bake file.
This patch ensures that all groups that are referenced inside the bake
file are actually defined under the groups field. This has required a
substantial refactor, as previously only a single group was returned
from ReadTargets, notably, returning a map of groups, instead of a
slice.
This does introduce a small behavior change to the behavior of --print -
while previously, passing a group name to bake would return all the
targets of that group back as the default group, now only the name of
that group will be inserted into the default group, keeping the original
group intact. The impact of this can be observed in some of the changes
to the bake_test.go file.
