android.resolveTargets ignores API level

[ypsvlq]

Zig's target encodes the API level (e.g. -Dtarget=aarch64-linux-android.26), which affects compilation as emutls is used for API levels below 29.

android.resolveTargets seems to always return API level 29, regardless of what is specified in the Zig target (or to sdk.createApk), which breaks threadlocal variables for lower API levels.

I think standardTargets/resolveTargets should be methods on Apk so they can infer the API level from there, allowing zig build -Dandroid=true -Dandroid_api_level=26 to work properly.

Hardcoding android_api_level = 28 in AndroidTargetQuery.queryTarget would also work as a temporary fix.
