fix: Fix chunked segment can not warmup using mmap

[sunby]

issue: #38410

[sunby]

ChunkedColumn does not use MmapChunkManager now so we use a file to mmap.
We will use MmapChunkManager to manage maped memory allocation and deallocation soon.

Use mmap manager?

Use mmap manager?

Chunk and ChunkedColumn will be changed a lot if I use mmap here. Will change it to MmapChunkManager later.
