Add a release config map override for go devices

This is a followup to https://r.android.com/3069967 and moves the
override map to v/google_shared/build/release. This allows sharing of
build flags between internal and partner builds.

Bug: 342265627
Test: presubmits
Test: verified that this map shows up in `get_build_var
PRODUCT_RELEASE_CONFIG_MAPS` of a go device
