  [CIR] Reuse BlockAddrInfoAttr in BlockAddressAttr

The constant `#cir.block_address` attribute stored its own `func` and
`label` parameters, duplicating `BlockAddrInfoAttr`, which already
bundles exactly that pair and is what the `cir.block_address`
operation takes.  Store a `BlockAddrInfoAttr` instead so the constant
and operation forms share one representation.

The textual format is unchanged (`#cir.block_address<@func, "label">`):
a small custom printer/parser flattens the embedded bundle so the two
forms keep printing the same way the operation does.  Call sites now
reach the function and label through `getBlockAddrInfo()`.
