soc/amd/glinda/cpu: Compute total L3 cache size

Glinda SoC has multiple L3 caches, each identified by a unique cache
UID. Each core is associated with a specific L3 cache, which can be
determined based on the CPU core ID.

The default implementation (x86_get_cpu_cache_info) retrieves cache
information only for the current core and assumes that the same L3 cache
is shared across all cores.

To accurately determine the total L3 cache size, this update:
1. Retrieves L3 cache information for each CPU core.
2. Identifies the unique cache ID associated with each core.
3. Aggregates cache sizes for all unique cache IDs to compute the total
   L3 cache size.

TEST=Build for Glinda SoC, with L3 cache = 16MB + 8MB. Ran command
'dmidecode -t 7' & verified L3 cache is 24MB.
