Migrate backdrop_filter_test.dart to use only widget imports following
issue #177415. Split the tests into two files:

- Widgets tests
(packages/flutter/test/widgets/backdrop_filter_test.dart):
  * Removed Material import, now uses widgets-only
  * Replaced MaterialApp + Scaffold with Directionality wrapper
  * Replaced Colors.black.withAlpha(40) with Color(0x28000000)
  * Kept 2 tests that validate BackdropFilter key behavior

- Material tests
(packages/flutter/test/material/backdrop_filter_test.dart):
  * Moved 4 Material-specific golden file tests (M2/M3 comparisons)
* These tests require Material theming to validate rendering differences

- Updated dev/bots/check_tests_cross_imports.dart to remove
backdrop_filter_test.dart

This approach keeps Material-specific tests in the material directory
while enabling the simple widget tests to pass without Material
dependencies.

Part of:  #177415
