Rollup merge of #110814 - WaffleLapkin:sprinkle_#inline, r=Nilstrieb

Sprinkle some `#[inline]` in `rustc_data_structures::tagged_ptr`

This is based on `nm --demangle (rustc +a --print sysroot)/lib/librustc_driver-*.so | rg CopyTaggedPtr` which shows many methods that should probably be inlined. May fix the regression in #110795.
