Add option to disable Scudo globally [Make] 

This adds an option to turn off Scudo globally, and use it for Go.

Bug: 123228023
Test: verify that Scudo is disabled for a Go build, eg:
lunch marlin_svelte-eng && m -j, check that Scudo is not linked in
out/target/product/marlin/system/bin/mediaextractor
Test: verify that Scudo is enabled otherwise, eg:
lunch marlin-eng && m -j, check that Scudo is linked in
out/target/product/marlin/system/bin/mediaextractor
