Single-file host tracing should include version and/or commit hash

[elinor-fung]

We intentionally do not set file version information for apphost and singlefilehost, since they represent the user's application. With apphost, we can still see the version and commit hashes in traces - for example:

--- Invoked apphost [version: 7.0.0, commit hash: d099f075e45d2aa6007a22b71b45a08758559f80] main = {
--- Invoked hostfxr_main_startupinfo [commit hash: d037e070ebe5c83838443f869d5800752b0fcb13]
--- Invoked hostpolicy [commit hash: d037e070ebe5c83838443f869d5800752b0fcb13] [runtime.win-x64.Microsoft.NETCore.DotNetHostPolicy,7.0.2,runtimes/win-x64/native][x64] corehost_main = {

For singlefilehost, we explicitly set this information to static:

runtime/src/native/corehost/setup.cmake

Lines 4 to 14 in ff12237

	if(CLR_SINGLE_FILE_HOST_ONLY)
	# CLR partition builds only the single file host where hosting components are all statically linked.
	# the versioning information is irrelevant and may only come up in tracing.
	# so we will use "static"
	add_definitions(-DHOST_POLICY_PKG_VER="static")
	add_definitions(-DHOST_FXR_PKG_VER="static")
	add_definitions(-DHOST_PKG_VER="static")
	add_definitions(-DCOMMON_HOST_PKG_VER="static")
	add_definitions(-DHOST_POLICY_PKG_NAME="static")
	add_definitions(-DHOST_POLICY_PKG_REL_DIR="static")
	add_definitions(-DREPO_COMMIT_HASH="static")

So all we have is:

--- Invoked apphost [version: static, commit hash: static] main = {
--- Invoked hostfxr_main_bundle_startupinfo [commit hash: static]
--- Invoked hostpolicy [commit hash: static] [static,static,static][x64] corehost_main = {

There doesn't seem to be any reasonable way to get at the version of the host is running. It is probably worth having a real value for at least either the version or commit so we can better understand what is being used when customers hit issues.
