Andreas Kling 9299d430c8 LibJS: Cache typed array data pointers for indexed access ...

Cache raw data pointers on fixed-length typed array views so asm
GetByValue and PutByValue can use them directly for indexed
element access.

Replace the asm typed-array hot-path
ArrayBuffer/DataBlock/ByteBuffer walk with one cached_data_ptr load.
Remove six unconditional loads, four branches, and the byte_offset
add before the element access, trading them for one
cached_data_ptr null check.

Keep direct C++ typed-array access on IsValidIntegerIndex-based
checks, invalidate cached pointers eagerly when a backing
ArrayBuffer is detached, and add regression coverage for shrink,
regrow, and detach on number and BigInt typed arrays.
