doc/next: populate TODOs found with relnote todo

Browse Source 
This is the first round of TODOs created based on relnote todo output.
There are many entries that need to be documented, expanded, reworded,
and this change makes progress on setting that up.

For this cycle, relnote todo implemented a simple heuristic of finding
CLs that mention accepted proposals (see issue 62376, or comment
https://go.dev/issue/62376#issuecomment-2101086794 specifically).
The "Items that don't need to be mentioned in Go 1.23 release notes but
are picked up by relnote todo." section in todo.md contains an attempt
at reviewing that list. The large number of items needed to be reviewed
made it impractical to spend much time on any individual one.

For #65614.

Go 1.23 makes two significant changes to the implementation of
[time.Timer] and [time.Ticker].
<!-- go.dev/issue/61542 -->
First, `Timer`s and `Ticker`s that are no longer referred to by the program
become eligible for garbage collection immediately, even if their
`Stop` methods have not been called.
Earlier versions of Go did not collect unstopped `Timer`s until after
they had fired and never collected unstopped `Ticker`s.

Second, the timer channel associated with a `Timer` or `Ticker` is
now unbuffered, with capacity 0.
The main effect of this change is that Go now guarantees
