nimble/host: Add support for ext adv param v2 HCI command

[rahult-github]

BLE spec version 5.4 introduced support for host to pass primary and secondary phy options in set extended advertising parameters. For this a new HCI command "HCI_LE_Set_Extended_Advertising_Parameters v[2] " with OCF 0x007F got introduced.

This patch adds support in host for this HCI command.

Hi @sjanc , @andrzej-kaczmarek , please let me know in case of any further comments

until now we didn't have need for V2 (or more) HCI commands in host but I think we should start tracking controller supported commands.

I believe we should be able to simply extend host API and if no preference is selected we can fallback to V1 if V2 is not supported, in case of preference set by app, we fail if V2 is not supported

So current implementation to read supported commands is only for event mask2 . I have extended it to use all commands bits ( so that future implementation can use it as needed).
