Specializer and interpreter should have same checks for vectorcall

[DinoV]

Bug report

Bug description:

When the specializer specializes a call to a python function it doesn't check if vectorcall is a non-default value, but the interpreter does. This leads to some spurious calls to go through the interpreter instead of through the functions vectorcall.

CPython versions tested on:

3.14

Operating systems tested on:

Linux
