binaryplatforms: Sort tags so `show` and `triplet` output is stable (#63169)

`show(::Platform)` and `triplet()` emitted extra tags in `Dict` iteration
order, which depends on insertion history rather than just on the tags
themselves. Two platforms that compare `==` could therefore produce
different `repr()` strings and triplets, e.g.
`x86_64-linux-gnu-tag1+1-tag2+2` versus `x86_64-linux-gnu-tag2+2-tag1+1`,
depending on the order in which the tags were passed or set. Sort tags by
key in both places so the output depends only on the platform's contents,
matching what the `text/plain` `show` method already did.

Extended tags in triplets are now always emitted in alphabetical order.
Parsing accepts them in any order, so existing triplets still parse.
