[executorch] Suppress wdeprecated warnings on tensor_layout.h and named_data_map.h

Context:
ET_EXPERIMENTAL is tagged with [[deprecated]]. This causes errors when ET_EXPERIMENTAL features are used in core ET and code is built with -Werror. See errors on D67127327.

This diff applies Option1 to 'tensor_layout.h' and Option2 to 'named_data_map.h'

Option 1:
- gate with `#pragma GCC diagnostic ignored "-Wdeprecated-declarations"`, for users of tensor_layout.h and program.h

Option 2:
- use ET_DISABLE_EXPERIMENTAL_ANNOTATION=1, for users of tensor_layout.h and program.h

----

Users
- tensor_layout.h: named_data_map.h
- named_data_map.h: method.h, program.h

Generally, I think we can apply either option1/option2 to `tensor_layout.h`.
For `named_data_map.h`, I think we should apply option2, to make ET_EXPERIMENTAL a no-op, or remove the ET_EXPERIMENTAL annotation to the implementation class. Option 1 would disable deprecation warnings for the entire file.
