[Patch v3 0/2] mm/huge_memory: Define split_type and consolidate split support checks

[Wei Yang <richard.weiyang@gmail.com>]

This two-patch series focuses on improving code clarity and removing
redundancy in the huge memory handling logic related to folio splitting.

The series is based on an original proposal to merge two significantly
identical functions that check folio split support[1]. During this process, we
found an opportunity to improve readability by explicitly defining the split
types. 

Patch 1: define split_type and use it
Patch 2: merge uniform_split_supported() and non_uniform_split_supported()

V3:
  * rebase on latest mm-new with Zi Yan fix [3]
  * introduce split_type to identify uniform/non-uniform split

V2: 
  * adjust comment
  * remove need_check

V1: [1]
