Add pfnGetArgumentProperties4 with 8D dims support and refactored argument properties struct

[jburcham-intel]

Summary

Adds a new graph argument properties query (ze_graph_argument_properties_4_t / pfnGetArgumentProperties4, extension v1.20) to support tensors with rank up to 8 (ZE_MAX_GRAPH_ARGUMENT_DIMENSIONS_SIZE_8), replacing the 5D cap in v3. Rather than just widening the existing struct, this cleans up accumulated redundancy/dead weight from v1-v3:

• networkPrecision/devicePrecision and networkLayout/deviceLayout collapse into single precision/layout fields reporting the compiled argument's properties — what callers actually need to allocate and bind buffers correctly.
• quantReverseScale/quantZeroPoint (added in v2, never consumed) are removed.
• The embedded associated_tensor_names array (char[32][256], ~8KB per query result) is removed from the struct entirely. A new pfnGetArgumentAssociatedTensorNames query replaces it, using the same query-size-then-fetch pattern already used by pfnGetNativeBinary / pfnGraphBuildLogGetString / pfnQueryNetworkGetSupportedLayers — no arbitrary name-count/length cap, and zero cost for the common case of an argument with no associated names.

Also adds ze_graph_argument_value_strides_2_t (new stype ZE_STRUCTURE_TYPE_GRAPH_ARGUMENT_STRIDES_2), an 8D-capable variant of ze_graph_argument_value_strides_t passed through the existing pfnSetArgumentValue2's pArgValue parameter, disambiguated by stype. This keeps the 8D story symmetric between reading argument properties and setting per-argument strides, without changing the layout of the existing 5D struct in place (widening a trailing array under a shared stype would be an unsafe ABI break for any driver/plugin version skew).

Changes

• Bump ZE_GRAPH_EXT_VERSION_CURRENT to 1.20; backfill missing ddi-table version placeholder comments for 1.17-1.19.
• New: ZE_MAX_GRAPH_ARGUMENT_DIMENSIONS_SIZE_8, ze_graph_argument_properties_4_t, pfnGetArgumentProperties4, pfnGetArgumentAssociatedTensorNames, ze_graph_argument_value_strides_2_t.
• New stypes: ZE_STRUCTURE_TYPE_GRAPH_ARGUMENT_PROPERTIES_4 (0x12), ZE_STRUCTURE_TYPE_GRAPH_ARGUMENT_STRIDES_2 (0x13).
• Clarified the pfnSetArgumentValue/pfnSetArgumentValue2 pArgValue doc comment to name each accepted struct type explicitly.
• Header-only change; no other files in this repo reference these types.

Maybe a pre-mature optimization, but it might make sense to also return number of names in the buffer, so the caller can reserve a vector or query the number of strings with pNames = NULL.
