Enable select syntax support for phony_deps in phony_rule

Previously, `phony_deps` in `phony_rule` was a simple []string type, so
the select syntax was not supported. This change modifies it to a
Configurable[[]string] type to enable select syntax support.

Bug: 354850153
Test: Add select syntax in the Andorid.bp
