wasi-cli import is sum of
WebAssembly/wasi-cli#19 and

* rename wasi-cli-base to wasi-cli, delete `preview` package, import wasi-cli

wasi-cli import is sum of
WebAssembly/wasi-cli#19 and
WebAssembly/wasi-cli#20

* wasi impl: change bindgen arguments and mod paths from cli_base to cli

* correct name of wasi-cli deps dir to just `deps/cli/`

it turns out this isnt semantically meaningful, since the package name
is in the document itself now, but lets be consistient

* track whether stdio isatty in ctx, and impl the cli/terminal-* interfaces

* rebase fixup

* wasi wits: define the reactor adapter's world

* component adapter: fixes

* test-programs/command-tests: fix renaming cli_base to cli

* component adapter: fix manually-defined export and import names

* test harness fixes

* preview1 component adapter: fill in isatty detection

* implement isatty in preview2-to-preview1 host adapter

* test-programs: cover both when stdio isatty and not

prtest:full

* split isatty test for regular file and stdio, detect host stdio is_terminal

CI environments vary - let the test runner make sure the host process's
stdio is in fact a terminal before asserting that the guest sees it is a
terminal.

* provide an is-terminal impl for all preview2's stdio types

which means making a newtype around Stdout and Stderr instead of using
a type alias there.

and then use the is-terminal impl to fill in the isatty field in the
builder when inheriting. if you need to override it you can always
builder.stdin(stdio::stdin(), your_own_idea_of_isatty)

* finally, rename IsATTY variants to Yes and No

* Fix the reference to IsATTY::No

* more forgotten renamings
