[indietyp]

🌟 What is the purpose of this PR?

Rename the PreInlining pass to PreInline for consistency with other transform passes in the codebase. This includes renaming the associated files, module references, and test directories.

🔍 What does this change?

• Renamed PreInlining class to PreInline in the MIR transform passes
• Renamed pre_inlining.rs file to pre_inline.rs
• Updated all import references to use the new name
• Moved test files from pre_inlining directory to pre_inline
• Updated suite name from "mir/pass/transform/pre-inlining" to "mir/pass/transform/pre-inline"
• Updated all function names and references from mir_pass_transform_pre_inlining to mir_pass_transform_pre_inline
