[PATCH ath-next v3 06/13] wifi: ath12k: ng: parse 1K REO queue statistics

A normal REO queue-statistics status contains the first 288 bits of the
reorder bitmap. For a receive queue with a larger BlockAck window, the
hardware sets a follow-up flag and returns bits 288 through 1023 in a
second status TLV.
Define the 1K queue-statistics status descriptor and decode its 23
additional bitmap words. Extend the common queue status with the PN
encoding, follow-up indication, and wider counters, and store the TLV tag
so a follow-on datapath patch can distinguish both responses for one
command number.
This commit only extends Wi-Fi 8 status representation and parsing. It
does not submit commands or change the Wi-Fi 7 descriptor path.
Tested-on: Compilation only, M=drivers/net/wireless/ath/ath12k
