hostapd: ubus get_status reports the spatial reuse settings

Browse Source 
The spatial reuse settings that a radio runs with were not visible at
runtime: get_status did not report them, and nl80211 does not carry
them. A radio with he_spr_sr_control=3 could not be told apart from an
unrestricted one.

get_status now adds, beside the BSS Color fields, at the top level and
in each entry of the links of an AP MLD, the running values of the
radio's configuration:
- he_spr_sr_control, he_spr_non_srg_obss_pd_max_offset,
  he_spr_srg_obss_pd_min_offset and he_spr_srg_obss_pd_max_offset, as
  numbers;
- he_spr_srg_bss_colors and he_spr_srg_partial_bssid, as the bitmap
  value with bit n for colour or partial BSSID n (IEEE Std 802.11-2024
  9.4.2.251), in 16 lowercase hex digits. The element holds the value
  little-endian; a ubus integer is signed, and colour 63 is bit 63.
  he_spr_srg_bss_colors=7 8 reads "0000000000000180".
