Subject: [PATCH] quiche: use PRIu64 for outputting the stream id

The 'id' struct field in 'struct h3_stream_ctx' is a uint64_t type so
should be output with PRIu64 - and it makes sense to be consistent.

Note that the field with the same name in the ngtcp2 version of this
struct is a *signed* 64-bit variable.

Closes #20849
