feat: Remove some long deprecated APIs

[gpeacock]

This removes some of the longer deprecated APIs:

Including:
Ingredient:
from_file
from_file_with_folder
from_file_with_options
from_memory
set_memory_thumbnail
IngredientOptions
DefaultOptions

c_ffi_api
c2pa_read_file
c2pa_read_ingredient_file
c2pa_sign_file

Store is not public but these methods were no longer used.
Store:
verify_from_path
load_jumbf_from_path

I also updated c2pattool and the client.rs example to not use the deprecated/removed methods.

Several unit and integration tests updated or removed due the the changes.
Removed if they were only testing things that no longer exist.

I will need a getter for base_path on Builder, like this: #2208
