Topdown level 1 and 2 for Intel Ice Lake (ICX). Limiting topdown support
to THREAD for the moment on Ice Lake, as NODE support is still
unreliable. Also removing Topdown Level 1 from Sapphire Rapids onwards,
as Topdown LeveL 2 also shows Level 1 on Sapphire, and it reduces the
overall number of bundles.

Rename the memory bandwidth bundle to memory stalls, to differentiate it
from the bundle that measures memory controller bandwidth boundedness.

Added an Intel Ice Lake specific bundles to measure pci bandwidth through the
Intel IO PMU. The "PCI" bundle measures read/writes from pci devices. The "CPU"
bundle measure read/writes from cpus to pci devices.

This code seems really usefull for reuse in
other plugins, for pretty table formatting

Added memory bandwidth boundedness bundle, closely related to cache-hierarchy.
This bundle works on ICX only, due to an ICX specific counter.

Callbacks for monitoring and performance measurement:
- Add new callback list type, with context
- Add callbacks for API, CLI, and barrier sync
- Modify node dispatch callback to pass plugin-specific context
- Modify perfmon plugin to keep PMC samples local to the plugin
- Include process nodes in dispatch callback
- Pass dispatch function return value to callback

Built a tool to chew up https://download.01.org/perfmon/mapfile.csv,
and output a table in this format:
typedef struct {
u8 model;
u8 stepping;
u8 has_stepping;
char *filename;
} file_by_model_and_stepping_t;
static const file_by_model_and_stepping_t fms_table [] =
{
/* model, stepping, stepping valid, file */
{ 0x2E, 0x0, 0, "NehalemEX_core_V2.json" },
{ 0x1E, 0x0, 0, "NehalemEP_core_V2.json" },
<snip>
{ 0x55, 0x5, 1, "cascadelakex_core_v1.00.json" },
{ 0x55, 0x6, 1, "cascadelakex_core_v1.00.json" },
{ 0x55, 0x7, 1, "cascadelakex_core_v1.00.json" },

The license issue is resolved, so we can package the .json
files. Added to the vpp-dev package in .tar.xz form, which saves a lot
of space.
Updated the perfmon error log entry: tell folks where to find the
compressed tarball, and how to extract it.
