[dvsim] Add support for second-level indirection
This adds support for a second level of indirection with the key-value
pairs in the HJson.
For example: lets say we supply the dict:
`{var: '{{foo}_xyz{bar}}', foo: p, bar: q, p_xyz_q: baz}`
Then after the substitutions above: `{var: '{p_xyz_q}', ...}`
We need to now substitute {p_xyz_q}, so that the final value of
`{var: 'baz', ...}`.
We will use this mechanism to set compile time values to keys that need
to be differentiated for each build. An example of where this will be
required to be done is setting different coverage collection hierarchy
files to different builds for the same DUT. In a subsequent PR, CSR
tests will have its own build and the coverage collected on those tests
will be significantly reduced. That PR will make this change probably a
bit clearer.

OpenTitan is an open source silicon Root of Trust (RoT) project. OpenTitan will make the silicon RoT design and implementation more transparent, trustworthy, and secure for enterprises, platform providers, and chip manufacturers. OpenTitan is administered by lowRISC CIC as a collaborative project to produce high quality, open IP for instantiation as a full-featured product. See the OpenTitan site and OpenTitan docs for more information about the project.
This repository contains hardware, software and utilities written as part of the OpenTitan project. It is structured as monolithic repository, or “monorepo”, where all components live in one repository. It exists to enable collaboration across partners participating in the OpenTitan project.
The project contains comprehensive documentation of all IPs and tools. You can access it online at docs.opentitan.org.
