wifi: rtw89: mcc: initialize start flow

We prepare to support TDMA-based MCC (multi-channel concurrency)
which allows two kinds of modes below.
* P2P GO + normal STA
* P2P GC + normal STA

Each mode has two vif and two chanctx. Then, each vif binds one
separate chanctx and becomes one MCC role. We name the two MCC
roles as follows.
* MCC role - reference (ref)
	We calculate the baseline of our TDMA things accodring
	to its info, e.g. TBTT. In normal case, it will be put
	at the first slot of TDMA.
* MCC role - auxiliary (aux)

MCC state machine will be running in FW eventually, but before that,
we have to fill and calculate things that are needed by FW. We fill
the information of MCC role according to its vif and its chanctx.
Then, we calculate the start time for MCC.

Note that the parameters used in the calculation now is assigned by
default rules. The precise parameters for better MCC behavior will be
derived in the following.
