Track the effective profile and crossgen state so incremental publishes rebuild every per-app R2R image when the mode changes. Validate profile paths, document the supported contract, and cover full/partial transitions plus browser execution in Wasm.Build.Tests.

Restore the browser optimization profile from the transport package and copy it into the WBT payload instead of committing a binary MIBC file. Share the same package profile with the JavaScript interop R2R tests. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Summary
WasmReadyToRunProfilefor CoreCLR browser applicationsIncremental publishing
The effective profile path and crossgen arguments are represented by a stable state hash. When that
state changes, all per-app R2R outputs are removed before crossgen runs. This prevents incremental
publishes from mixing full and partial images, including when switching back to a previously used
configuration.
