GuC snapshot output is currently expensive in both size and latency: large
log buffers are emitted as raw ascii85, and the surrounding dump text
includes a bit of avoidable noise. This series makes xe snapshot dumps more
compact and easier to handle by compressing the large binary payloads,
tightening the textual output, and trimming the default GuC log size.

Select ZSTD_COMPRESS in DRM_XE so the xe module pulls in the zstd
compressor when built.

History:
v6: Remove intermediate build files(Julia)
    Remvoe unnecessary comment(Julia)
v5: Update cover letter messages to remove shrink log size.
    Fix kernel-doc warning.
v4: Remove ZSTD_DECOMPRESS dependency.
v3: Add Kconfig option to control compression of GuC log and CTB dumps,
    allowing users to choose between reduced dump sizes or lower memory
    usage.
    Remove "reduce GuC log size from 8MB to 2MB" patch, to be added later
    if needed.
    Replace pr_err with xe_gt_err and add more error print.
v2: Fix Kunit test error by selecting ZSTD_DECOMPRESS in DRM_XE config,
    required by zstd_is_error/zstd_get_error_name.
