[v4 10/24] cli_simple: Rework this support slightly

[Tom Rini]

The interactive portion of our non-HUSH 'simple' parser is guarded by
CONFIG_CMDLINE already.  Much of the code behind this simple parser is
also used as "input" parser, such as from menu interfaces and so forth
and not strictly command line input.  To support this, always build the
assorted cli object files, but guard the interactive portions of
cli_simple.c with a CMDLINE check.
