Jaskaran Singh e12dcc29cc ANDROID: Configure out the macros in android_kabi and android_vendor ...

Add configs to control removing the macros or not. On some platform,
configureing out the macros removes the associated members from the
structs, this reduces the object size of the slabs related with the
structs, therefore reduces the total slab memory consumption of system.

Besides, this also reduces vmlinux size a bit, therefore the total
kernel memory size increses a bit.

The macros are ANDROID_KABI_RESERVE, ANDROID_VENDOR_DATA,
ANDROID_VENDOR_DATA_ARRAY, ANDROID_OEM_DATA, ANDROID_OEM_DATA_ARRAY.
