Fix incompatible MSVC options being passed through to nvcc

[matthewdcong]

nanobind adds /bigobj and /MP as compiler options for MSVC which results in this issue previously seen in pybind11.

pybind/pybind11#3883

The same fix has been ported over in this PR.

Should something similar be done related to size optimizations? I remember vaguely that nvcc doesn't like -Os

[matthewdcong]

The current workaround for that is passing NOMINSIZE to nanobind_add_module. However, that applies to the whole module as opposed to individual translation units so it really depends if we want the finer grained control.

[wjakob]

Could you modify the patch so that the default (pass -Os unless NOMINSIZE is specified) is handled differently so that nvcc works out of the box? Then this PR would be complete in the sense that it handles all nvcc-related oddities.

[matthewdcong]

Sure, sounds good.

Done

Thanks!
