[FEATURE] Topology builder 2.0

[lgirdwood]

Is your feature request related to a problem? Please describe.
M4 topology allows for pre-processing and generation of topology alsa conf format but does not allow easy validation, semantic or syntax checking.

Describe the solution you'd like
1st pass - Use M4 for preprocessing of "include" and "define" of constants.
2nd pass - Develop parser for where topology can be validated alongside semantic and syntax checking. The parser should support a "keyword" definition language where new topology keywords can be added alongside rules for their use.
3rd pass - Current topology compiler.

@mmaka1 which format does the eclipse plugin use for topology data ? We will need to make sure cmd line and GUI tools can work alongside each other.

Work in progress by @lyakh - see #3211

@ranj063 fyi - moved to v1.8 as this is likely where we will intercept with current WiP working well.
