Move target_cpu into use_rbe block in Fuchsia build (#179458 )

The `target_cpu` local is only used if `use_rbe` is true. Move its
definition into the `use_rbe` block to avoid local build issues like

```
$ ninja -C engine/src/out/ci/fuchsia_debug_arm64
ERROR at //build/toolchain/fuchsia/BUILD.gn:13:19: Assignment had no effect.
  target_triple = "aarch64-unknown-fuchsia"
                  ^------------------------
You set the variable "target_triple" here and it was unused before it went
out of scope.
```

Flutter Engine

The Flutter Engine is a portable runtime for hosting Flutter applications. It implements Flutter's core libraries, including animation and graphics, file and network I/O, accessibility support, plugin architecture, and a Dart runtime and compile toolchain. Most developers will interact with Flutter via the Flutter Framework, which provides a modern, reactive framework, and a rich set of platform, layout and foundation widgets.

More tooling is available to make development experiences easier:

Target	Tool
Web	`felt`
Mobile or Desktop	`et`

To learn about running tests, see testing the engine.
