Revert "Revert "Convert dexdeps-docs to Soong.""

This reverts commit 2458d73c.

Reason for revert:
Convert dexdeps-docs to Soong, attempt 2.

Previously attempt 1 broke aosp-master/ndk targets since I use java_binary with host_supported:true which caused the issue:
out/soong/build.ninja:1865875: multiple rules generate out/soong/target/product/generic_arm64/system/bin/dexdeps [-w dupbuild=err

Now switched to java_binary_host to disable device build, and it passed in my local machine.

Test: m clean && OUT_DIR=out build/soong/scripts/build-ndk-prebuilts.sh
Bug: b/70351683
