For all the commands that call Initialise, we introduce a new flag:
UseSequential.
This disables DAG scheduling for evaluating datasources and locals as a
fallback to the newly introduced DAG scheduling approach.
`hcl2_upgrade` is a special case here, as the template is always JSON,
there cannot be any datasource, so the DAG in this case becomes
meaningless, and is not integrated in this code path.
The enumeration for FlagSetFlags, which presumably was added when the
Meta structure was introduced, aims to pre-populate the flagset for a
subcommand with a series of arguments.
However, despite it being documented, it is actually not used, and
therefore can safely be removed from the codebase.

It is not clear that the console command runs in legacy JSON mode by
default and that users can specify the -config-type flag to toggle HCL2
mode. This change adds the config-type flag to the command's help text
to alert users of the gotcha.
In the next minor Packer release the console command will be updated to
default to HCL2 mode.

The initialization of packer core in JSON also validates that `null` variables were set, except in the case of `packer validate --syntax-only` , but after the refactor to allow to have all commands work with HCL2 and JSON this subtlety was lost.
This refactors the initialisation of the core in order to allow to have `packer validate --syntax-only` not error in case a variable is not set. Since these calls are refactored this works for HCL2 too.
