alias targets should expose FilesToRunProvider if actual has one

[illicitonion]

Description of the bug:

I have code which runs a cquery to gets the executable of a FilesToRunProvider:

bazel cquery --output=starlark --starlark:expr="providers(target).get(\"FilesToRunProvider\").executable.path"

This doesn't work for alias targets which point to binary targets. It probably should.

What's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.

BUILD file:

py_binary(
    name = "bin",
    srcs = ["bin.py"],
)

alias(
    name = "alias",
    actual = ":bin",
)

Run: bazel cquery --output=starlark --starlark:expr="providers(target).get(\"FilesToRunProvider\").executable.path" :alias

expect to get an output path. Instead, get an error because providers(target).get("FilesToRunProvider") is None.

Which operating system are you running Bazel on?

What is the output of bazel info release?

release 6.1.0

If bazel info release returns development version or (@non-git), tell us how you built Bazel.

Seems to be a much more general issue:

$ bazel cquery --output=starlark --starlark:expr="providers(target)" :alias
None
