Amx flag removal (#16527)

### Description
1. Replacing AMX intrinsics with machine code macros in QGEMM kernel.
2. Removing AMX build flags for GCC in cmake file.
3. Fixing the link time optimization (LTO) issue introduced with asm
.include of an assembly file.

I have moved the AMX instruction macro definitions from
QgemmU8S8KernelAmxCommon.S to the amx_common.h to fix the LTO issue.
Note that I am also pushing the macros defined in
QgemmU8S8KernelAmxCommon.S for future reference.

A special thanks to @laxmansole who helped in the development of the
instruction macro definitions for AMX intrinsics and fixing the LTO
issue.

### Motivation and Context
The additional AMX flag in cmake adds an extra layer of dependency on
GCC version to use the feature.These changes should allow the usage of
the AMX feature with just the CPU ID check.
