fix: checking if struct/array element is contiguous

[cieplypolar]

Changes

• sizeOf cache was expanded to include information for contiguousness and longest prefix (and renamed)
• original method was renamed to computeMemoryLayout
• sizeOf, isContiguous and getLongestContiguousPrefix are now exported from individual files
• tests for new methods and getOffsetInfoAt
• some oxlint adjustments

Motivation

Our current approach for calculating the longest contiguous block starting at given offset doesn't work

For example

We should return 28 instead of 16

Pull request overview

This PR fixes incorrect contiguous memory block calculations for struct and array elements by refactoring the memory layout computation system. The previous implementation couldn't correctly determine the longest contiguous block of memory starting at a given offset, particularly for nested structures with padding.

Changes:

• Refactored memory layout computation into a unified system that tracks size, contiguousness, and longest contiguous prefix together
• Added new exported functions isContiguous() and getLongestContiguousPrefix() for querying memory layout properties
• Fixed the contiguous region calculation in offsetUtils.ts to properly handle non-contiguous struct and array elements

File	Description
packages/typegpu/src/data/schemaMemoryLayout.ts	New file implementing unified memory layout computation with caching for size, contiguousness, and longest contiguous prefix
packages/typegpu/src/data/sizeOf.ts	Simplified to delegate to the new getLayoutInfo system
packages/typegpu/src/data/isContiguous.ts	New file exporting isContiguous function to check if a type has no padding
packages/typegpu/src/data/getLongestContiguousPrefix.ts	New file exporting function to get the size of the longest contiguous memory prefix
packages/typegpu/src/data/offsetUtils.ts	Updated to use new isContiguous and getLongestContiguousPrefix functions; fixed struct run detection to end at non-contiguous fields

packages/typegpu/src/data/alignmentOf.ts	Fixed vector bool type literals from short aliases to full canonical form
packages/typegpu/tests/offsetUtils.test.ts	Updated test expectations with corrected contiguous values (e.g., 28 instead of 16) and added edge case tests
packages/typegpu/tests/isContiguous.test.ts	Comprehensive test coverage for the new isContiguous function across all data types
