please rename to wasi-clock or wasi-time

wasi-clocks is awkward, as mentioned in https://www.youtube.com/watch?v=e21pDhJ8vPc I would like to follow the naming conventions here for some package/scope concerns. So, it would be nice to rename it to something and settle on that. Probably wasi-clock or wasi-time. The first was suggested by @sunfishcode though I personally prefer the latter. It is bikeshed so no hard opinion except to firm up what it will be.

Another relevant proposal is wasi-sockets.

for wazero, we are going with clock as it is clock_time_get not clocks_time_get. whatever naming choice should lean towards function names, packages, or enclosing filenames, IMHO
