[nxp][platform][mcxw71_k32w1] Relocate key storage default option to example apps args definition files (#36577)

The GN args file for the MCXW71/K32W1 platforms defines a default
for the "nxp_nvm_component" option which prevents the users from
selecting a different option in the command line. The default value
for this build option is already defined by the

third_party/nxp/nxp_matter_support/gn_build/nxp_sdk.gni

GN arguments file. If one would want to override the default, this
has to be done in the scope of the application so that the user can
also override the build option from the command line.
