* Add GEMM examples for int4 Currently the source files are just copied from int8 examples * Re-use pre-defined alias in int4 exmples * Distinguish user-side type from kernel-side type * Add int4_t support for check_err() * Allow conversion between Tensor<> specializations * Re-format source files * Use different type for host tensors * Re-use CopyAsType<>() to implement copy ctor * Re-use element-wise operation type alias * Fix typo in alias names * Complete the int4 examples * Add constraint to Tensor<> templated methods * Add type traits 'is_signed_integral<>' * Add type constraints for integer version check_err<>() * Allow comparing different-sized integral types in check_err() * Check converted Tensor<int4_t> with golden Tensor<int8_t> * Remove constraint of Tensor<>::CopyAsType() * Avoid compilation error while disabling ck::int4_t support * Remove debug messages * Add #error directive to prevent compile sources with wrong setting * Simplify tensor usages in examples * Add constraint to check_err() input reference type * Align design with other PR * Use ""_uz to simplify example code * Avoid too much generalizing check_err() * Re-format GEMM instance template arguments * Extract int4 example common codes * Sort include directives * Move #include directives into new header * Move common codes together * Re-format template argument in example code * Reuse same implementation code for most of GEMM examples * Re-format common.hpp * Unify structured comment in examples * Use reinterpret_cast<>() for cross-type pointer conversion * Revert "Add type traits 'is_signed_integral<>'" This reverts commitf2c148efae. * Allow unsigned integer arguments for check_err() * Fix compilation error in check_err() * Remove unnecessary copy ctor for Tensor<> * Mark Tensor<> special member functions as 'default' * Use more strict condition to add code in examples * Fix wrong program return value of GEMM examples * Handle the case while user specify all the strides * Fix never-ran examples * Exit successfully if GEMM instance does not support given problem * Add missing 'else' keyword * Re-format CMakeLists.txt * Add wrapper function to hide value conversion while copying memory * Add new DeviceMem API to copy memory * Use new DeviceMem API to implement examples * Revert "Add new DeviceMem API to copy memory" This reverts commit3f190b0779. * Add conversion ctor for Tensor<> * Write Tensor<> conversion logics explicitly in example code * Convert Tensor<> values after transfer data to host [ROCm/composable_kernel commit:fa2d894be1]

Caveat
Kernel Timing and Verification
CK's own kernel timer will warn up kernel once, and then run it multiple times to get average kernel time. For some kernels that use atomic add, this will cause output buffer to be accumulated multiple times, causing verfication failure. To work around it, do not use CK's own timer and do verification at the same time. CK's own timer and verification in each example and ckProfiler can be enabled or disabled from command line.
