[Variant] [Shredding] Support typed_access for `Utf8` and `BinaryView`

• Part of [EPIC] [Parquet] Implement Variant type support in Parquet #6736

We are implementing Variant support in arrow-rs (🎉 ), and we are currently implementing "shredding" - the ability to read Variants when they have been partially extracted into a type value column.

This ticket tracks adding support for accessing typed values of the type listed in the description of this ticket as a Variant value

Describe the solution you'd like

Fix the corresponding test cases in the shredded_variant test suite.

After #8325 is merged, you can run that suite using:

cargo test --all-features --test variant_integration

Describe alternatives you've considered

1. Extend typed_value_to_variant for the type (source link)
2. Add an appropriate test case, following the models of tests such as

arrow-rs/parquet-variant-compute/src/variant_get/mod.rs

Lines 442 to 445 in fb7d02e

	#[test]
	fn get_variant_partially_shredded_uint8_as_variant() {
	numeric_partially_shredded_test!(u8, partially_shredded_uint8_variant_array);
	}
