[KUBE-50] gpuagent: add GPUGetFilter to skip GPU attribute groups on …

[bhatturu]

…GPUGet

Port pensando/sw#119031 onto the GIM 9.1.0.K base. GPUGetRequest carries an optional GPUGetFilter of 11 per-attribute Skip* flags (unset fetches all). aga_gpu_read/read_all/gpu_entry::read take the filter and pass it to the smi fill paths; each collector in the amdsmi, gimamdsmi and mock backends is gated by its Skip* bit (AGA_GPU_SKIP). gpuctl gains --skip-* flags.

This lets a client (DME) drop the expensive KFD process walk and other unneeded collectors from the default GPUGet path (KUBE-50).

(cherry picked from commit 46a5c25)
