Description

When trying to build the feast go lib on ppc64le it fails because parquet internal seems to miss even the basic (pure go implementations for ppc64le) files. Providing e.g. `bit_packing_ppc64le.go` & `unpack_bool_ppc64le.go` should solve this issue in the first place.

It can then be enhanced by implementing the correct vector & matrix intrinsics for the Power architecture (e.g. VSX or MMA) in a second step.

go build -mod=mod -buildmode=c-shared -tags cgo,ccalloc -o embedded_go.so .
cmd had error: exit status 2 output:

/root/go/pkg/mod/github.com/apache/arrow/go/v8@v8.0.0/parquet/internal/utils/bit_reader.go:318:18: undefined: unpack32 

I tested this already locally (with success) and create an according PR.
