[receiver/sqlserver]update resources attributes to export identifying attributes (open-telemetry#39449)

<!--Ex. Fixing a bug - Describe the bug and how this fixes the issue.
Ex. Adding a feature - Explain what this achieves.-->
#### Description

We used to export those attributes on the log level, this is not
alignihg with the semantic convention, also, the old way will cause
waste of disk resources, as we can group them to a higher level to avoid
repeat them all the places.

<!-- Issue number (e.g. open-telemetry#1234) or full URL to issue, if applicable. -->

+component: sqlserverreceiver
+
+# A brief description of the change.  Surround your text with quotes ("") if it needs to start with a backtick (`).
+note: "`host.name`, `sqlserver.computer.name`, and `sqlserver.instance.name` are now resource attributes instead of log attributes. We used to report `computer_name` and `instance_name` in the log attributes for top query collection and they are now deprecated. Now we report the three resources attributes in both top query collection and sample query collection."

+# Mandatory: One or more tracking issues related to the change. You can use the PR number here if no issue exists.
+issues: [39449]
+
+# (Optional) One or more lines of additional information to render under the primary note.
+# These lines will be padded with 2 spaces and then inserted directly into the document.
+# Use pipe (|) for multiline entries.
+subtext: This change is only relevant for logs.
