Before this commit, enum values were serialized as attributes of form

This has multiple drawbacks:
  * Enums with large values would be hard to process for downstream
    tooling that cannot parse arbitrary precision decimals. (In fact
    Yosys also did not correctly process enums with large values,
    and would overflow `int`.)
  * Enum value attributes were not confined to their own namespace,
    making it harder for downstream tooling to enumerate all such
    attributes, as opposed to looking up any specific value.
  * Enum values could not include x or z, which are explicitly
    permitted in the SystemVerilog standard.

After this commit, enum values are serialized as attributes of form

Suppress output of Makefile.conf when printing source versions

The make targets echo-yosys-ver, echo-git-ver and echo-abc-rev can be
used to programmatically extract contents of make variables for external
scripts. Unfortunately, when a Makefile.conf exists, its contents would
also be echoed, making the output almost unusable. This patch
selectively disables this functionality for these special targets.
