Colin Cross 0f86d186b1 Allow AndroidMkData.Custom handlers to extend normal values
Pass accumulated AndroidMkData to AndroidMkData.Custom handlers
and expose WriteAndroidMkData so that Custom handlers can write
out the normal make variables and then add their own.

Test: No change to out/soong/Android-aosp_sailfish.mk
