Generic integration memory peripheral

[mtdudek]

Generic integration creates memory mapped device.

This is the third and last PR in the series of 3. It requires #1177

It adds concept of managers, they are responsible for translating memory type accesses to stream operations. They are also responsible for lifetime of the channel wrappers. There are 3 types of manager:

• SingleValue,
• Stream,
• DMA.

This PR also adds top level XlsPeripheral class. It's responsible for:

• reading configuration file,
• initializing IR simulation,
• configuring managers,
• redirecting memory operations to correct channel manager,
• advancing simulation.

should we close this and favor of reviewing the demonstrator at https://github.com/antmicro/xls-cosimulation-demonstrator ?

we can then re-open a new PR once we figure out how to integrate the simulator build w/ the bazel workspace.

Closing this PR in the favour of the demonstrator repo.
