refactor `DataView`, `TypedArray`, `ArrayBuffer` indices to use `usize`

[zhuzhu81998]

The usage of u64 vs usize is not unified for indices of the types backed by ArrayBuffer.
We want to use usize wherever possible.

For example:

boa/core/engine/src/object/builtins/jsdataview.rs

Lines 180 to 186 in 27959b2

	/// Returns the `byte_offset` field property of [`JsDataView`] as a u64 integer
	#[inline]
	pub fn byte_offset(&self, context: &mut Context) -> JsResult<u64> {
	DataView::get_byte_offset(&self.inner.clone().upcast().into(), &[], context)
	.map(|v| v.as_number().expect("byte_offset value must be a number") as u64)
	}

boa/core/engine/src/builtins/array_buffer/mod.rs

Lines 200 to 213 in 27959b2

	/// The internal representation of an `ArrayBuffer` object.
	#[derive(Debug, Clone, Trace, Finalize, JsData)]
	pub struct ArrayBuffer {
	/// The `[[ArrayBufferData]]` internal slot.
	#[unsafe_ignore_trace]
	data: Option<AlignedVec<u8>>,
	/// The `[[ArrayBufferMaxByteLength]]` internal slot.
	max_byte_len: Option<u64>,
	/// The `[[ArrayBufferDetachKey]]` internal slot.
	detach_key: JsValue,
	}
