RFR(XS): 8211837: Creation of the default CDS Archive should depend on ENABLE_CDS

Hi Martin, Goetz,

thanks for reviewing my patch! As Aleksey posted a similar patch for
fixing the Zero build I've extended my patch to handle
zero/minimal/core as well.

In fact the patch now disables CDS on AIX, minimal, core and zero
unless the user explicitly requests it with the help of
`--with-jvm-features=cds`. The configuration variant with
`--with-jvm-features=-cds` should now also be handled correctly (I
hope caught all possible combinations :)

If CDS is disabled, the creation of the default class list and default
archive will now be disabled as well.

@Aleksey Shipilev : can you please check if this new version of my
patch also works for you?


Thank you and best regards,
