  Unreviewed build fixes for RISCV64
https://bugs.webkit.org/show_bug.cgi?id=253700

Unreviewed build fixes for RISCV64 builds of JavaScriptCore.

* Source/JavaScriptCore/assembler/MacroAssembler.h: Enable the moveFloat and
moveDouble methods that work with immediate values, sharing the scratch register
variant with x86-64.
* Source/JavaScriptCore/offlineasm/riscv64.rb: Also generate WASM placeholders
for the loadv and storev opcodes, used in WebAssembly.asm.
* Source/WTF/wtf/PlatformEnable.h: Avoid further compilation issues by enabling
ENABLE_WEBASSEMBLY_B3JIT alongside ENABLE_WEBASSEMBLY.
