qcom: add squashed version of a530 zap shader

Qualcomm binary files can be published in one of two formats: a split
MDT+Bnn format, consisting of several files, or a squashed MBN format,
consisting of a single ELF file.

Most of Qualcomm binary files (except the venus firmware) are
distributed (in linux-firmware) and used in the MBN format (even if the
original publishing format was MDT), since that requires transfer of a
single file between the userspace and the kernel.

Provide a squashed variant of Qualcomm Adreno a530 ZAP shader.  For
backwards compatibility reason the split a530_zap.* files are retained.
They can be removed later, after all users migrate to new file location.
