In handle_let_and_var.cpp, field initializers are now handled like regular `var` initializers, by calling `LocalPatternMatch`. In pattern_match.cpp, `FieldDecl`s with initializers are handled by storing a value in `SemIR::File::field_initializers()`. This is a new map where the keys are `FieldDecl` `InstId`s and the map values are `InstId`s representing the initializer value. In convert.cpp, `ConvertStructToStructOrClass` now has a `get_default` function parameter that callers can use to provide a field default. `ConvertStructToClass` uses this to provide a default from field initializers.
