ANDROID: tvgki: disabling CONFIG_DEBUG_INFO_BTF in tvgki

Browse Source 
If we check the large allocation usage by kmalloc(), we can find the large allocation usage can be reduced at least 3MB while disable CONFIG_DEBUG_INFO_BTF.

CONFIG_DEBUG_INFO_BTF=y @ Launcher
[  227.946779]Sunreclaim is 148756 KB
[  227.954747]    large_allocation_size is 8880 KB
[  227.962729]    unreclaim slab is 140056 KB

CONFIG_DEBUG_INFO_BTF is not set @ Launcher
[   63.768458]Sunreclaim is 128308 KB
[   63.773973]    large_allocation_size is 5904 KB
[   63.780476]    unreclaim slab is 123512 KB

So, 8880KB - 5904KB ==> almost 3000KB memory usage is reduced (@ kernel 6.12)
