In preparation for making it easier to write topology conf files that
can be conditionally included without having to worry about conflicting
node ID's for objects between the included file and the top-level conf
file, modify all classes to include an instance attribute. This means
that irrespective of the object type, all objects will be instantiated
as follows:
Object.Widget.gain.1 {} or Object.Base.pdm_config.2 {} etc
The instance ID's are typically only meant for the alsatplg compiler to
differentiate the nodes in the conf file and are not relevant for the
kernel or the firmware. This change will allow the alsatplg compiler to
be modified to automatically make the node ID's unique before
conditionally including conf files.

It's now possible to rebuild just only one modified topology without
rebuilding all of them from scratch.
Building topologies v2 has two steps:
1. concatenation of abi.conf with topo.conf
2. run alsatplg on the concatenation
Concatenation step 1. was wrongly implemented at configuration time, not
at build time. So when the topology source of step 1 (topo.conf) was
modified, the dependency of step 2 (= the concatenation) was not
affected and the topology was not rebuilt.
Fix this by moving the concatenation to build time.
Fixes commit 308a24a92b ("topology2: Add build support")

The major/minor/patch values are represented with u16 in the FW. So,
change the numbers of bytes to match that of the FW when adding the
ABI to the topology manifest for IPC4. For IPC3, we still only use 3
bytes as there's no clean way to increase the number of bytes without
breaking backwards compatibility with the older kernel. There are no
topologies using topology2 for IPC3 today but it is possible in the
future.

Add build support for topology2. Topology2 will be built only if the
alsatplg version if 1.2.6 or greater.
