  [WebGPU] Implement Buffer::getMappedRange in Swift

Reviewed by Mike Wyrzykowski.

Add a Swift version of Buffer::getMappedRange and the computeRangeSize helper
function. The implementation is disabled by default. The patch forward declares
`wtf::Range` as a workaround, as importing `<wtf/Range.h>` caused build failures.

Verified that webgpu:api,validation,buffer,mapping:* passes. Also fixed the
precondition in Swift's Buffer::copy as some of the tests were crashing.
