Bugfix/fix bluetooth bt tool async gap moudle cb change to const

[huangyulong3]

Memory Optimization: Change the bluetooth bt_tool async gap module to const for reduce the ram size.

bug:v/84961

Rootcause: To reduce RAM resource consumption, the le_conn_options, g_set_cmd_tables,
g_get_cmd_tables and g_pair_cmd_tables in the bt_tools async gap module must be marked with the const modifier.
This ensures it is compiled and linked into Flash memory instead of RAM.

Pull request overview

This pull request implements a memory optimization for Bluetooth tools by adding the const qualifier to static data structures across multiple files. The optimization moves read-only data structures from RAM to Flash memory, reducing RAM consumption as described in bug v/84961.

Changes:

• Added const qualifier to static command tables (bt_command_t arrays) and option arrays (struct option arrays) in tools modules
• Added const qualifier to static callback structures (e.g., advertiser_callback_t, bt_conn_cb, bt_hfp_hf_cb) across service layers
• Added explicit casts to remove const when passing these structures to functions that don't accept const pointers (API compatibility)
