perf(allocator): add #[inline(always)] to trivial RawVec methods

[overlookmotel]

These methods are trivial, and should always be inlined. Probably compiler will anyway, but make sure by adding #[inline(always)] attributes, same as for RawVec's other trivial methods.

Pull Request Overview

This PR adds inline attributes to several methods in RawVec and corrects documentation to accurately reflect the implementation. The changes improve performance by enabling aggressive inlining of simple accessor methods and constructor functions.

• Adds #[inline(always)] to four simple methods: new_in, from_raw_parts_in, ptr, and bump
• Adds #[inline] to the private current_layout method
• Corrects documentation comment for ptr() method to reference NonNull::dangling() instead of the outdated Unique::empty()
