Rollup merge of #64528 - Aaron1011:fix/proc-macro-type, r=alexcrichton

Load proc macro metadata in the correct order.

Serialized proc macro metadata is assumed to have a one-to-one
correspondence with the entries in static array generated by proc_macro_harness.
However, we were previously serializing proc macro metadata in a
different order than proc macros were laied out in the static array.
This lead to us associating the wrong data with a proc macro when
generating documentation, causing Rustdoc to generate incorrect docs for
proc macros.

This commit keeps track of the order in which we insert proc macros into
the generated static array. We use this same order when serializing proc
macro metadata, ensuring that we can later associate the metadata for a
proc macro with its entry in the static array.

Fixes #64251
