enhance: add disk file writer with Direct IO support (#43692)
issue: #43040
pr: #42665 

This patch introduces a disk file writer that supports Direct IO.

Currently, it is exclusively utilized during the QueryNode load process.

Below is its parameters:

1. `common.diskWriteMode` This parameter controls the write mode of the
local disk, which is used to write temporary data downloaded from remote
storage. Currently, only QueryNode uses 'common.diskWrite*' parameters.
Support for other components will be added in the future.
The options include 'direct' and 'buffered'. The default value is
'buffered'.

2. `common.diskWriteBufferSizeKb` Disk write buffer size in KB, only
used when disk write mode is 'direct', default is 64KB.
Current valid range is [4, 65536]. If the value is not aligned to 4KB,
it will be rounded up to the nearest multiple of 4KB.

3. `common.diskWriteNumThreads` This parameter controls the number of
writer threads used for disk write operations. The valid range is [0,
hardware_concurrency]. It is designed to limit the maximum concurrency
of disk write operations to reduce the impact on disk read performance.
For example, if you want to limit the maximum concurrency of disk write
operations to 1, you can set this parameter to 1.
The default value is 0, which means the caller will perform write
operations directly without using an additional writer thread pool. In
this case, the maximum concurrency of disk write operations is
determined by the caller's thread pool size.

Both parameters can be updated during runtime.
