Subject: Machine type related general changes
This patch is first part of original "Add RHEL machine types" patch we
split to allow easier review. It contains changes not related to any
architecture.

- Rewrite machine compat properties to upstream solution
Rebase changes (4.1.0):
- Removed optional flag for machine compat properties (upstream)
- Remove c3e002cb chunk from hw/net/e1000.c
- Reorder compat structures
- Use one format for compat scructures
- Added compat for virtio-balloon-pci.any_layout for rhel71
Rebase changes (weekly-210303):
- Added rhel 8.4.0 compat based on 5.2 compat
Rebase changes (weekly-211103):
