ANDROID: gki: Enable CONFIG_AUTOFDO_CLANG

Browse Source 
This config enables AutoFDO for the kernel.

When an AutoFDO profile isn't provided, this config
only adds more debug info for profiling. This results
in a slight increase (0.5%) in vmlinux size. This extra
debug info is stripped with other debug info when building
boot image. So it's safe to leave this config always
enabled.

When an AutoFDO profile is provided, this config builds
the kernel with the profile.

Bug: 382743224
Test: build arm64 & x86_64
