tcg: introduce **tcg_ctxs to keep track of all TCGContext's



Groundwork for supporting multiple TCG contexts.

Note that having n_tcg_ctxs is unnecessary. However, it is
convenient to have it, since it will simplify iterating over the
array: we'll have just a for loop instead of having to iterate
over a NULL-terminated array (which would require n+1 elems)
or having to check with ifdef's for usermode/softmmu.
