Release hmsdk v4.0

This is a new release for hmsdk v4.0, which supports enhanced bandwidth
and capacity expansion as well as bwprof, which is a bandwidth profiling
tool.

The changes from hmsdk v3.0 to v4.0 are as follows.

1. Bandwidth expansion enhancement
- support multi-socket weighted interleave
  - with socket-aware weighted interleave
  - with this feature, users don't have to use "-N/--cpunodebind nodes"
    option to numactl to avoid UPI overhead between sockets
    - instead, "numactl -w all" is all you need now
- support weighted interleave APIs in libnuma
  - the following APIs for weighted interleave is added to libnuma
    - numa_alloc_weighted_interleaved_subset()
    - numa_alloc_weighted_interleaved()
    - numa_weighted_interleave_memory()
- hmctl supports -w/--weighted-interleave option
  - to support object level weighted interleave (e.g. malloc level)
    - libnuma APIs are page level weighted interleave (e.g. mmap level)

2. Capacity expansion enhancement
- support multi-threaded monitoring and migration
  - to enhance monitoring accuracy and migration speed
  - by multiple kdamonds covering split ranges of whole address

3. bwprof tool for system memory profiling
- system-wide bandwidth profiling tool for both DRAM and CXL memory
- it supports top, record, report, dump, and info commands for monitor,
  record and analyze the result offline

4. notable submodule and tools update
- linux kernel: upgrade from v6.12 to v6.17
  - with socket-aware weighted interleave feature on top of v6.17
- damo: upgrade from 2.4.7 to 3.0.0
- numactl: upgrade to 548e9ea for new libnuma APIs
- move damo and numactl submodules into tools directory
- mlc: upgrade from v3.11 to v3.12
- remove tools/gen_config.py symbolic link to tools/gen_migpol.py
