Move amdsmi from 'base/' folder and artifact to 'amdsmi' artifact in 'core/'

[ScottTodd]

Per discussion at #2045 (comment), we would like to move the amdsmi subproject from its current location in https://github.com/ROCm/TheRock/tree/main/base to https://github.com/ROCm/TheRock/tree/main/core.

This will allow amdsmi to depend on the clang toolchain we build instead of the system compiler so ASan builds can be enabled. It will also unblock #2045 which moves therock-googletest (one of amdsmi's deps) to be configured after "base" (but still before "core"). See the include order here:

TheRock/CMakeLists.txt

Lines 459 to 464 in 2e9e168

	# Add subdirectories in dependency DAG order (which happens to be semi-alpha:
	# don't be fooled).
	add_subdirectory(third-party)
	add_subdirectory(base)
	add_subdirectory(compiler)
	add_subdirectory(core)

Quoting @stellaraccident from that thread:

If we do that, we should create an amdsmi artifact vs lumping it into "base". It needs to be its own and will need its own package, etc (so I think this was done as-is in error).

I'd love to further eliminate base/ entirely but we can get there eventually.

Some code to change:

• TheRock/base/CMakeLists.txt

  Line 175 in 2e9e168

  list(APPEND _optional_subproject_deps amdsmi)

• TheRock/base/artifact.toml

  Lines 5 to 20 in 2e9e168

  	# amdsmi
  	[components.dbg."base/amdsmi/stage"]
  	optional = "windows"
  	[components.dev."base/amdsmi/stage"]
  	optional = "windows"
  	[components.doc."base/amdsmi/stage"]
  	optional = "windows"
  	[components.lib."base/amdsmi/stage"]
  	optional = "windows"
  	[components.run."base/amdsmi/stage"]
  	optional = "windows"
  	include = [
  	"bin/**",
  	"libexec/**",
  	"share/amd_smi/**",
  	]
