What problem does this PR solve?

Issue Number: ref #5294

What is changed and how it works?

optimize agg with collation
- add ITiDBCollator::compareFastPath and ITiDBCollator::sortKeyFastPath to check bin collation as fast path
- add std::unique_ptr<AggregationMethodMultiStringNoCache<AggregatedDataWithStringKey>> multi_key_string; to handle agg functions whose keys are all strings.
use inline_memcpy(libs/libcommon/include/common/memcpy.h) to accelerate memory copy for small buff
replace default memcpy with __folly_memcpy(libs/libmemcpy/folly/memcpy.S)
replace default memory comparison functions of StringRef with internal implementation.

MemUtils

Test memory copy

__folly_memcpy, benefited from avx2 instructions, performs better when string size is not small(>80 Bytes)
the new implementation of inline_memcpy is better than original one(from Clickhouse).
