wifi: iwlwifi: mvm/fw: Avoid -Wflex-array-member-not-at-end warnings

-Wflex-array-member-not-at-end was introduced in GCC-14, and we are
getting ready to enable it, globally.

We have a flexible struct iwl_tx_cmd_v6 in the middle of a few structs,
but those don't even need the flexible part.

So, we add iwl_tx_cmd_v6_params, that will contain everything except the
flexible array and use this one for the containing structs.

Also, as part of the refactoring remove unused flex array `payload`.

So, with these changes, fix the following warnings:

drivers/net/wireless/intel/iwlwifi/mld/../fw/api/tdls.h:134:27: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]

wifi: iwlwifi: use normal versioning convention for iwl_tx_cmd

We have iwl_tx_cmd for devices older than 22000, iwl_tx_cmd_gen2 for
22000 devices, and iwl_tx_cmd_gen3 ax210 and up.

But the convention for all other APIs is to have the latest version
without any prefix and the older ones - with a _vX prefix,
where X is the highest version that this struct support.

The term 'gen' was introduced as the name of the (back then) new
transport, and should not be used as a device name (for that we have the
actual names: 22000, ax210, etc.)

Now as a new transport, called 'gen3', is going to be written and it can
be confused with this API.

Move iwl_tx_cmd to use the regular versioning convention.

This isn't necessary, there are many more of those than MACs,

and on 9000 series it'll be in struct iwl_cfg but be ignored
when the CRF is in a Qu/So platform.
