Types like uuid.UUID implement encoding.TextUnmarshaler but previously
required an explicit `parser=encoding.TextUnmarshaler` struct tag to be
used during form/query/URI binding. This meant ShouldBind/ShouldBindQuery
would fail with unhelpful errors like:
["45e1f85e-bca5-458d-bd9c-c56edd8f847b"] is not valid value for uuid.UUID
This change makes trySetCustom automatically check for
encoding.TextUnmarshaler as a fallback after BindUnmarshaler,
so any type implementing TextUnmarshaler (uuid.UUID, net.IP,
custom types, etc.) works out of the box with no extra tags.
Precedence order:
1. BindUnmarshaler (UnmarshalParam)
2. encoding.TextUnmarshaler (UnmarshalText)
3. Default type-based binding
time.Time is explicitly excluded from automatic TextUnmarshaler
handling since gin has dedicated time parsing with time_format,
time_utc, and time_location struct tags.

- 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.

* test(form): fix test code for array collection format in form binding
The pointer support in url query params (using []*Struct for binding query params) was previously available in Gin, but was removed in commit 0d50ce8 since there wasn't a test case for such a scenario, and so the case block was removed as a redundant one.
