the unit test doesn't define a working_dir so path generate on Windows is escaped
this use case is already covered and tested by compose-go CI

Change FS entitlements checks from warning to error
by default as expressed in initial PR. Users can still
opt-out with environment variable if the choose to.

This changes how the composable attributes are implemented and provides
various fixes to the first iteration.
Cache-from and cache-to now no longer print sensitive values that are
automatically added. These automatically added attributes are added when
the protobuf is created rather than at the time of parsing so they will
no longer be printed. If they are part of the original configuration
file, they will still be printed.
Empty strings will now be skipped. This was the original behavior and
composable attributes removed this functionality accidentally. This
functionality is now restored.
This also expands the available syntax that works with each of the
composable attributes. It is now possible to interleave the csv syntax
with the object syntax without any problems. The canonical form is still
the object syntax and variables are resolved according to that syntax.

Currently, to compare the local path used by bake against the paths allowed
by entitlements, symlinks were evaluated for path normalization so that the
local path used by build was allowed to not exist while the path allowed by
entitlement needed to exist. If the path used by the build did not exist,
then the deepest existing parent path was used instead. This was concistent
with entitlement rules as that parent path would be the actual path access
is needed.
This raised an issue with `--set` if one provides a non-existing path as
an argument, as these paths are supposed to be allowed automatically. With
the above restrictions set to allowed paths, this meant the build would fail
as it can't grant entitlement to the non-existing paths.
This changes the evaluation logic for allowing paths so that they do not
need to exist. If such a case appears, then the path is evaluated to the
last component that exists, and then the rest of the path is appended as is.
This means that for example, if `output = /tmp/out/foo/` is set in HCL
and `/tmp` is the last component that exists then invoking build with
`--allow fs.write=/tmp/out/foo` will not fail with stat error anymore
but will fail in entitlements validation as build would also need to
write `/tmp/out` that is not inside the allowed `/tmp/out/foo` path. The
same would apply to `--set` as well so that if it points to
a non-existing path, then an additional `--allow` rule is needed
providing access to writing to the last existing component of that path.
This may or may not be unexpected.
