target/ppc: make power8-pmu.c CONFIG_TCG only 

This is an exclusive TCG helper. Gating it with CONFIG_TCG and changing
meson.build accordingly will prevent problems --disable-tcg and
--disable-linux-user later on.

We're also changing the uses of !kvm_enabled() to tcg_enabled() to avoid
adding "defined(CONFIG_TCG)" ifdefs, since tcg_enabled() will be
defaulted to false with --disable-tcg and the block will always be
skipped.
