[Tracking]: unified path normalize behavior

[hardfist]

Background

let's define two kinds of path first

• unc path: \\?\C:\foo
• none unc path(or regular path): C:\foo

currently we have three ways to deal with path normalize, and they're all different

• std canonicalize: transform all path to unc format
• dunce::canonicalize dunce::simplified: try best to transform all path to none unc format
• sugar_path normalize: if input is unc then output is unc, if input is none unc then output is none unc, which is nearly the same as nodejs normalize behavior

mix usage of unc path and regular will cause hard to debug bugs, so it would be better to unified path format in rspack

Suggestions

all the input path(means all the path not generated from other normalize behavior) should be normalized with dunce::simplified (which is performance friendly since it doesn't touch IO, credits to @hyf0 suggestion), and all the following normalized path derived from input path should use sugar_path normalize(which is also fast cause it doesn't touch IO).
we should forbid use std canonicalize in all cases.
