wifi: cfg80211: add PD-specific preamble and bandwidth capabilities

Devices may support different preamble and bandwidth configurations for proximity detection (PD) ranging versus standard ranging. Add separate pd_preambles and pd_bandwidths fields to cfg80211_pmsr_capabilities to allow drivers to advertise PD-specific capabilities. Expose these over nl80211 using new attributes NL80211_PMSR_FTM_CAPA_ATTR_PD_PREAMBLES and NL80211_PMSR_FTM_CAPA_ATTR_PD_BANDWIDTHS, advertised only when pd_support is set. For PD requests, validate bandwidth and preamble against pd_bandwidths and pd_preambles. For non-PD requests, validate against the existing bandwidths and preambles fields.
