[Bug] uninitialized member vars

[vagetablechicken]

Describe the bug
There are some ctors which have uninitialized member vars.
And we do miss set value to them.
e.g. #3750

Because UTs link to the static libs of src, so gcc warning -Wuninitialized can't help us. But UBSAN can.

To Reproduce
Steps to reproduce the behavior:

1. build ut with UBSAN, and run test
2. we may find runtime error: load of value XX, which is not a valid value for type 'YYY'. It's usually because we use the uninitialized vars.

Expected behavior
No the load of value error log.
I'll fix:

1. RowBlockInfo::null_supported
2. BlockManagerOptions::enable_metric
3. TabletColumn::all bool member vars

Additional context
We should be careful about uninitialized vars. May need more ut.
