add aliases support to shell integration

[cpendery]

I'd like if vscode's shell integration allowed injecting command aliases from the settings.json file. It would be really helpful to allow projects with a range of shells/os's to share a common set of commands

Settings.json

{
  "terminal.integrated.shellIntegration.aliases":  {
    "gp": "git push"
  }
}

Pwsh Injected Command

function __VSCode-<aliasName>() {
  <aliasCommand> $args
}
Set-Alias -Name '<aliasName>' -Value '__VSCode-<aliasName>'

Bash/Fish/Zsh Injected Command

alias <aliasName>='<aliasCommand>'

I'm not that keen on the idea of us injecting this stuff for set up native shell aliases. However, this is very close to the run recent command pin feature:

As well as the snippets idea I've had for a while; essentially aliases that show up in the suggest widget which would work similarly to snippets in the editor:

This is something I had in mind as particularly useful for copilot chat suggestions.

Sounds good, snippets are a cool idea!

Having per-project aliases would be awesome! This way we could avoid littering our repositories with scripts that must be locally gitignored, and polluting our global aliases via system-wide shell configuration.
