fix: align ts_project(data) runfiles with js_library(data)

[jbedard]

After removing the use of js_library the ts_project(data) no longer conditionally goes through js_library(data) when the transpiler attribute is set. However the js_library(data) was creating the runfiles differently then ts_project_rule(data).

This change makes ts_project(data) align with the defaults of js_library(data) to restore the previous behaviour.

I'm afraid this is a breaking change for usages of ts_project without a custom transpiler:

copy_data_files_to_bin = True comes with the caveat that it is source files coming from a different package are not allowed in data.

This breaks a basic filegroup:

# package //files
filegroup(
  name = "files",
  srcs = [...],
)

# package //code
ts_project(
  data = ["//files"],  # this will break with this change.
)
