Do not override setting of SOONG_CONFIG_<m>_module_source_build

Previously, any setting of SOONG_CONFIG_<m>_module_source_build (where
<m> is one of wifi, uwb or bluetooth) that was made before the
core/android_soong_config_vars.mk was processed would be replaced with
false. This change will only set them to false if they have not been
previously set.

Bug: 233965247
Test: m nothing
      # After setting SOONG_CONFIG_wifi_module_source=true before this
      # code. Without this change out/soong/soong.variables uses false
      # for the wifi_module/module_source config variable. With this
      # change it uses true.

Android Make Build System

This is the Makefile-based portion of the Android Build System.

For documentation on how to run a build, see Usage.txt

For a list of behavioral changes useful for Android.mk writers see Changes.md

For an outdated reference on Android.mk files, see build-system.html. Our Android.mk files look similar, but are entirely different from the Android.mk files used by the NDK build system. When searching for documentation elsewhere, ensure that it is for the platform build system -- most are not.

This Makefile-based system is in the process of being replaced with Soong, a new build system written in Go. During the transition, all of these makefiles are read by Kati, and generate a ninja file instead of being executed directly. That's combined with a ninja file read by Soong so that the build graph of the two systems can be combined and run as one.
