### What problem does this PR solve?

Related PR: #40680

Problem Summary:

This pull request temporarily disables session tracking and automatic
cleanup for temporary tables due to a memory leak issue involving
`Env#sessionReportTimeMap` and `Env#aliveSessionSet`. The affected logic
is commented out with TODO notes, and related imports are cleaned up.

Session management changes:

* Disabled the code that adds sessions to `aliveSessionSet` in
`Env.registerSessionInfo`, preventing new session tracking until the
memory leak is fixed.
* Disabled the code that updates session report times in
`Env.refreshSession`, pausing session activity tracking.

Temporary table cleanup changes:

* Commented out the logic in `TemporaryTableMgr.runAfterCatalogReady`
that deletes temporary tables when their creating session is gone,
halting automatic cleanup.
