Add support for venv --prompt (#1570)
## Summary

This PR adds the `--prompt` option to `venv` subcommand.

The default behavior for `uv venv` is to create a virtual environment in
the current directory with `.venv` name. This is different from `venv` /
`virtualenv` where a user always needs to provide the virtual
environment path. This allows us to define our own behavior in the
default scenario (`uv venv`). We've decided to use the current
directory's name in that case.

Workflows:
| Command | Virtual Environment Name | Prompt |
|--------|--------|--------|
| `uv venv` | `.venv` (default) | Current directory name |
| `uv venv project` | `project` | `project` |
| `uv venv --prompt .` | `.venv` | Current directory name |
| `uv venv --prompt foobar` | `.venv` | `foobar` | 
| `uv venv project --prompt foobar` | `project` | `foobar` | 


Fixes #1445

## Test Plan

This is my first Rust code and I don't know how to write tests yet.
I just checked the behavior manually:

```
$ cargo build
$ mkdir t
$ cd t
$ ../target/debug/uv venv -p 3.11
$ rg -w t .venv/bin/acti*
.venv/bin/activate.csh
13:setenv VIRTUAL_ENV '/Users/inada-n/work/uv/t/.venv'
20:if ('t' != "") then
21:    setenv VIRTUAL_ENV_PROMPT 't'
23:    setenv VIRTUAL_ENV_PROMPT "$VIRTUAL_ENV:t:q"
38:    # in which case, $prompt is undefined and we wouldn't

.venv/bin/activate
48:VIRTUAL_ENV='/Users/inada-n/work/uv/t/.venv'
59:    VIRTUAL_ENV_PROMPT="t"

.venv/bin/activate.fish
61:set -gx VIRTUAL_ENV '/Users/inada-n/work/uv/t/.venv'
73:if test -n 't'
74:    set -gx VIRTUAL_ENV_PROMPT 't'

.venv/bin/activate.ps1
40:if ("t" -ne "") {
41:    $env:VIRTUAL_ENV_PROMPT = "t"

.venv/bin/activate.nu
6:# but then simply `deactivate` won't work because it is just an alias to hide
35:    let virtual_env = '/Users/inada-n/work/uv/t/.venv'
50:    let virtual_env_prompt = (if ('t' | is-empty) {
53:        't'
```
