Cannot choose some combinations of the CPU topology values

[hstastna]

Description of a problem:
In the current web-ui, it is not possible to set all the valid combinations of the values for the number of sockets, cores, threads, according to the total VCPUs. For example, for 9 total VCPUs, it is not possible to reach the CPU topology with 1 socket, 1 core and 3 threads. This should be possible in both Create VM Wizard's Basic settings and also in VM Details card.

Steps to Reproduce:

In webadmin it works, it is possible to choose any valid combination of the values.

This whole CPU topology fields validation is not so user friendly as well since in case of an error, the user can't understand what is the exact invalid cpu topology - the values are auto changed to some different invalid values than the original values entered by the user.

Not sure if worth fixing as a standalone issue but maybe as part of this fix if possible.
