fix: moving STREAM_SOURCE_MAP to out.global in server side

[bill-min]

Description

Having STREAM_SOURCE_MAP in module will cause issue when there is concurrency where the second request coming before the micro-frame-slot is reading STREAM_SOURCE_MAP. Also storing STREAM_SOURCE_MAP in module will make it persist in server and can cause memory issue.

Motivation and Context
