GoWeb: add service container into Gin's engine and context

- Use specified default value in struct tags when binding a request input to struct for validation, even if sent empty, not only when not sent at all.
- Add string field to `TestMappingDefault` test case.
- Add test case for not sent form field to default to the value specified via code.
- Add test case for form field sent empty to default to the value specified via code.

Fixes: How to apply default value if empty value provided by client during model binding? #4042, #13042df, #a41721a

+
+NOTE: For default [collection values](#collection-format-for-arrays), the following rules apply:
+- Since commas are used to delimit tag options, they are not supported within a default value and will result in undefined behavior
+- For the collection formats "multi" and "csv", a semicolon should be used in place of a comma to delimited default values
+- Since semicolons are used to delimit default values for "multi" and "csv", they are not supported within a default value for "multi" and "csv"
