android-tools-conf-configfs: make USB gadget IDs configurable

Browse Source 
The android-gadget-setup script currently hardcodes the USB vendor ID,
product ID, and configuration string. This makes it difficult for BSP
layers to customize USB gadget identity with platform specific values.

Introduce variables for the vendor ID, product ID, and configuration
string when populating the configfs attributes. This allows machine
or distro specific overrides via `/etc/android-gadget-setup.machine`,
while preserving the existing default values.
