metal: per-op source split + parallel compile (#26561)

• metal : per-op source split + parallel compile (#24021)

• preliminary extract common header

• op source split

• split metallib into 8 libs && load in parallel

• derive kernel->library routing from functionNames

• x-macro lib list + underscore filenames, dedup QK_NL, MRC fixes

• op source split 8 to 20

• improve robustness of source fallback

• clean up

• change bool -> atomic_bool

• only prepend headers that source actually includes

• no semaphore, use GCD global queue

• dedup library compile path, fix NSError lifetime, rename gla

• relocate upstream concat/rope_back/repeat kernel changes into split files

• move ggml-common.h from common.h into dequantize.h to shrink binary size

• metal: add col2im_1d op (f32/f16/bf16) (#25176)

• metal : add set_rows with src0 f16 (#25434)

• metal : add CONV_2D_DW (depthwise convolution) support (#21565)

• metal : add Q2_0 support (#25419)

• metal: fuse snake activation (mul, sin, sqr, mul, add) (#25459)

• ggml-metal: FWHT kernel for metal backend (#25924)

• metal : port new kernels into the split sources

Move the kernels added on master after the split (lightning indexer,
DSv4 hyper-connections, silu_back, f16 bin ops, TQ2_0, the flash-attn KV
dequantization pass, rope offset/inplace, ssm_scan rollback, packed q8_0
dequantization and the tensor-API mat-mat K clamp) into the corresponding
kernels/*.metal sources. Copied verbatim, no functional change.
