feat: Rename --unstable-hmr to --watch-hmr (#24975)

Browse source 
This commit stabilizes HMR functionality and renames
`--unstable-hmr` to `--watch-hmr`. The `--unstable-hmr`
flag is still working, but hidden from the help output.
It will be removed in Deno 2.

Once https://github.com/denoland/deno/pull/24958 lands
we should improve grouping of `--watch` and `--watch-hmr`
flags.
