Previous check based on dest attributes was not correct
as the attributes already get converted before validation happens.
Because the local path is not preserved for single-file
outputs and gets replaced by io.Writer, a temporary array variable
was needed. This value should instead be added to ExportEntry
struct in BuildKit in future revision.

Raise the maximum size limit for the dockerfile and correct the size
check. The size check was intended to use the size attribute from the
file stat, but the original gogo version confused the `Size()`
method (which returned the size of the proto message) with the `Size`
attribute (which was named `Size_`).
During the conversion, we noticed the mistake but kept the incorrect
behavior for the sake of keeping the conversion simple.
This also raises the maximum limit because 512 kB is likely a bit too
conservative. The limit has been raised to 2 MB and the limit has been
included in the error message.

Removes gogo/protobuf from buildx and updates to a version of
moby/buildkit where gogo is removed.
This also changes how the proto files are generated. This is because
newer versions of protobuf are more strict about name conflicts. If two
files have the same name (even if they are relative paths) and are used
in different protoc commands, they'll conflict in the registry.
Since protobuf file generation doesn't work very well with
`paths=source_relative`, this removes the `go:generate` expression and
just relies on the dockerfile to perform the generation.

Not all the error cases from getGitAttributes returned
appendNoneFunc. When nil was returned it caused a panic.

When building from same stream all nodes need to read
data from the same stream. In order to achive that there
is a new SyncMultiReader wrapper that sends the stream
concurrently to all readers. Readers must read at similar
speed or pauses will happen while they wait for each other.
Dockerfiles were already written to disk before sent. Now
the file written by first node is reused for others.

Some errors can appear without a stacktrace or progress record,
eg. wrong Dockerfile name passed. In that case when building many
targets with bake it might be hard to figure out which target
failed as in the progressbar there will only be steps that
were cancelled.

Detect cases where multiple bake targets would use the same
local source. For such cases a separate session request is
made in addition to session per target and local source
is made available in that source as well.
The new sessionID is sent with the request so the frontend
can ask associate it with the local source it needs.
The sources are still available in the main request session
as well. This would be used if frontend ignores the local-sessionid
parameter and makes sure that old version continue working.

This is a preparation to shared local sources for bake
targets and makes it possible to have equality check
between locals from different targets.

When LocalDirs were changed to LocalMounts, this broke the
sharedKey computation that was based on the context directory
path. SharedKey defines if directory is valid candidate for
incremental context transfer and if not set properly then
different directories do metadata-based transfers to same destination.
