[PATCH v5 02/18] libcamera: software_isp: Move BlackLevel to libcamera::ipa::soft

[Milan Zamazal]

IPA modules use custom namespaces for all their internal components to
avoid namespace clashes. The simple IPA module for the software ISP uses
libcamera::ipa::soft for this purpose. It however defines an internal
class named BlackLevel in the root of the libcamera namespace, making it
prone to clashes. Move it to the ipa::soft namespace along with the rest
of the code.
