[SETUPLIB][REACTOS][USETUP] Finish unification of MBR extended and primary/logical partitions

Browse source 
Fixes previous attempt at commit 0ca4e6dcf, which was reverted by commit
bbdcc14b1 because the partitioning checks mistook unpartitioned disks as
GPT.

Addendum to commit 99f0937fd.

The partition-creation checks are unified for these partitions into one
single function. To prepare for GPT support, the specifics are put into
a separate MBRPartitionCreateChecks() helper, called for MBR disks by the
upper-level function. GPT disks will have a similar helper in the future.
