* [regression-test](Variant) Add more cases related to schema changes
And fix bugs about schema change for variant:
fix bug schema change crash on doing schema change with tablet schema that contains extracted columns
* [DNM](decimal) use new way for decimal arithmetic precision promotion
* [improvement](decimal) [DNM](decimal) use new way for decimal arithmetic precision promotion
1. [DNM](decimal) use new way for decimal arithmetic precision promotion
2. throw exception if it overflows for decimal arithmetics
3. throw exception if it overflows when casting among number types
* fix compile error of gcc
* improvement

1. limit the column count to default 2048
2. fix get_inverted_index return nullptr when variant's unique id is -1, using it's parent unique id instead
3. avoid add same path subcolumn duplicately in tablet schema
4. make extracted column unique id -1
Improve the performance under the tpch data set by reconstructing the join related code and the use of hash table

Manually track query/load/compaction/etc. memory in Allocator instead of mem hook.
Can still use Mem Hook when cannot manually track memory code segments and find memory locations during debugging.
This will cause memory tracking loss for Query, loss less than 10% compared to the past, but this is expected to be more controllable.
Similarly, Mem Hook will no longer track unowned memory to the orphan mem tracker by default, so the total memory of all MemTrackers will be less than before.
Not need to get memory size from jemalloc in Mem Hook each memory alloc and free, which would lose performance in the past.
Not require caching bthread local in pthread local for memory hook, in the past this has caused core dumps inside bthread, seems to be a bug in bthread.
ThreadContext life cycle to manual control
In the past, ThreadContext was automatically created when it was used for the first time (this was usually in the Jemalloc Hook when the first malloc memory), and was automatically destroyed when the thread exited.
Now instead of manually controlling the create and destroy of ThreadContext, it is mainly created manually when the task thread start and destroyed before the task thread end.
Run 43 clickbench query tests.
Use MemHook in the past:
1.Reconstruct the logic of decode to read parquet. The parquet reader first reads the data according to the parquet physical type, and then performs a type conversion.
2.Support hive alter table.
Fix work load group GC, add cancel load and add logs.
Unify the format and change all to lowercase of GC logs, avoid unnecessary trouble when grep or less
Add logs to help locate the cause of slow GC.
After memory exceeds the limit, print the top 15 task trackers with the largest memory.
After memory exceeds the limit, more detailed GC logs in stages.
fix large memory check.
