Libero - Add flexible TCL script hooks

This allow adding TCL scripts on pre-synthesize, pre-pnr and
pre-bistream generation for the Libero backend.

In the .core file, this would be defined like:

```yaml
  polarfireeval:
    files:
      - rtl/corescore_polarfire_eval_clock_gen.v: { file_type: verilogSource }
      - rtl/corescore_polarfire.v: { file_type: verilogSource }
      - data/polarfire_eval.pdc: { file_type: PDC }
      - data/script_pre_synth.tcl: { file_type: tclSourcePresynth }
      - data/script_pre_pnr.tcl: { file_type: tclSourcePrepnr }
      - data/script_pre_bitstream.tcl: { file_type: tclSourcePrebistream }
```
