wifi: iwlwifi: mvm: clean up duplicated defines

VHT, HE and EHT rates use the same bits for NSS, so no need for
defines per PHY version.

Also use spatch to replace bit manipulation with FIELD_GET:

@@
identifier rate;
@@
-((rate & RATE_MCS_NSS_MSK) >> RATE_MCS_NSS_POS)
+FIELD_GET(RATE_MCS_NSS_MSK, rate)

wifi: iwlwifi: rs: add support for parsing max MCS per NSS/BW in 11be

Rate scale needs to be configured to what MCS it can use per BW and NSS,
this is done by parsing our capabilities of TX and peer's capabilities of
RX and setting the minimum for rate scale usage.

Also do some cleanup removing redundant enum defines not used by
FW/Driver.

iwlwifi: fix iwl_legacy_rate_to_fw_idx

There are a couple of bugs in this function:

1. It is declared as a non-static function, even though
it's only used in one file.
2. Its return value should be of type u32 but it returns
(in some cases) -1.

Fix them by making this function static and returning an
error value of type unsigned.

In addition, we're assigning the return value of this function
as the legacy rate even if the function returned an error value.
Fix this by assigning the lowest rate in this case.

iwlwifi: reorganize firmware API

Apart from DVM, all firmware uses the same base API, and there's
code outside iwlmvm that needs to interact with it. Reflect this
in the source better and reorganize the firmware API to a new
fw/api/ directory.

While at it, split the already pretty large fw-api.h file into a
number of smaller files, going from almost 3k lines in there to
a maximum number of lines less than 1k.
