Use mojom `|` conditionals for mixed build conditions

Mojom now supports `|` and `&` when testing `EnableIf` and
`EnableIfNot` conditions in mojom files. Previously, to
support multiple conditions, a build.gn file would define
a specific `enabled_feature`:

```build.gn
if (is_linux || is_win) {
  enabled_features += [ "is_linux_or_win" ]
}
```

This can now be handled directly in the mojom:

```mojom
  [EnableIf=is_linux|is_win]
  struct Foo {
    ...
  };
```

This CL applies this build.gn simplification where mixed
OS conditionals have been defined, and where no corresponding
build flag exists in the .cc/.h source (i.e. the .cc file
uses `BUILDFLAG(IS_WIN)||BUILDFLAG(IS_LINUX)`).

There should be no functional changes.
