Fix DWARF binary not copied for AppleDsymBundleInfo

[luispadron]

From what I can tell the AppleDebugInfo provider correctly gives us the binary paths, the only difference is that AppleDsymBundleInfo seems to add a /dSYMS/ directory path:

AppleDsymBundleInfo: bazel-out/<sha>/bin/Code/Apps/CashAppWidgets/WidgetExtension/dSYMs/WidgetExtension_dsyms/Widget Extension.appex.dSYM
AppleDebugInfo:      bazel-out/<sha>/bin/Code/Apps/CashAppWidgets/WidgetExtension/WidgetExtension_dsyms/Widget Extension.appex.dSYM

It looks like thats intentional given:

rules_apple/apple/internal/partials/debug_symbols.bzl

Lines 330 to 332 in afd97b7

	# Put the tree artifact dSYMs in a subdirectory to avoid conflicts with the legacy dSYMs
	# provided through existing APIs such as --output_groups=+dsyms.
	dsym_bundle_dir = actions.declare_directory("dSYMs/" + dsym_bundle_name)

But then the rule copies it without the /dSYMS:

rules_apple/apple/internal/partials/debug_symbols.bzl

Lines 132 to 137 in afd97b7

	output_binary = actions.declare_file(
	"%s/Contents/Resources/DWARF/%s" % (
	dsym_bundle_name,
	debug_output_filename,
	),
	)

Is it possible to add a test for this?

@mattrobmattrob updated and added tests for the xcarchive rule to ensure these are now getting copied (these tests were previously failing without this change)
