omrope79 37c9ab1815 Merge pull request #29226 from omrope79:fix_mlas_x86
Fix MLAS 32-bit x86 build by integrating missing upstream assembly files #29226

### Pull Request Readiness Checklist

This resolves the 32-bit x86 build failure for MLAS. Related to: https://github.com/opencv/opencv/pull/29218

* Added the required `x86` assembly files and headers from upstream.
* Added `__x86_64__` guards around the AMX `syscall` and the FMA3/AVX512F kernel assignments to prevent 32-bit compilation crashes.

See details at https://github.com/opencv/opencv/wiki/How_to_contribute#making-a-good-pull-request

Routine Description:
This routine is an inner kernel to compute matrix multiplication for a
set of rows.
Arguments:
A - Supplies the address of matrix A.
B - Supplies the address of matrix B. The matrix data has been packed using
MlasSgemmCopyPackB or MlasSgemmTransposePackB.
C - Supplies the address of matrix C.
CountK - Supplies the number of columns from matrix A and the number of rows
from matrix B to iterate over.
CountM - Supplies the maximum number of rows that can be processed for
matrix A and matrix C. The actual number of rows handled for this
invocation depends on the kernel implementation.
CountN - Supplies the number of columns from matrix B and matrix C to iterate
over.
lda - Supplies the first dimension of matrix A.
ldc - Supplies the first dimension of matrix C.
Alpha - Supplies the scalar multiplier (see SGEMM definition).
ZeroMode - Supplies true if the output matrix must be zero initialized,
else false if the output matrix is accumulated into.
Return Value:
Returns the number of rows handled.
