[PATCH 4/8] build: Remove CONFIG_HAS_PDX

[Alejandro Vallejo <alejandro.vallejo@cloud.com>]

It's set everywhere and can't be turned off because it's presence is
assumed in several parts of the codebase. This is an initial patch towards
adding a more fine-grained CONFIG_HAS_PDX_COMPRESSION that can actually be
disabled on systems that don't typically benefit from it.

No functional change.
