android: Add V8 no-WASM code GC experiment switch

Introduce a Java switch, V8_NOWASM_CODE_GC, to enable the V8 flag
--nowasm-code-gc. This provides a mechanism to disable WebAssembly
code garbage collection.

The primary purpose is to allow experimental evaluation of whether
disabling WASM code GC can help avoid specific high volume crashes.

A comprehensive test suite for JavaSwitches is also added.
