wpewebkit: update to version 2.52.3

Browse Source 
Update WPEWebKit to the 2.52 stable major release branch.

Includes a pending patchset to get WASM BBQJIT working on RISCV64,
upstream PR https://github.com/WebKit/WebKit/pull/65621

Alltogether this brings acceptable performance (even with LLVMPipe
Mesa software renderer) on RISCV64.

Subject: [PATCH] JavaScriptCore: BBQJIT: implement wasm tail call on RISCV64
emitTailCall (direct) and emitIndirectTailCall in WasmBBQJIT.cpp branch
on the host CPU to set up the caller's frame pointer + return address
for the tail-jumped callee. ARM64/ARMv7 use loadPairPtr(fp, callerFP, lr)
to read both at once; X86_64 has its own dedicated branch; everything
else trips UNREACHABLE_FOR_PLATFORM() -> SIGABRT during BBQ compilation
of any wasm function that uses return_call (tail call).
RISC-V's standard prologue saves fp and ra adjacent at [sp, sp+8]
(same layout as ARM64), so the ARM64 loadPair64-backed loadPairPtr
also works on RISCV64. The "fix SP and FP" sequence (addPtr to
stackPointerRegister + move callerFramePointer -> framePointerRegister)
is also generic. Add CPU(RISCV64) to all three guarded branches.
Reproducer: spec-tests/try_table.wast.js line 117
(assert_exception(() => call($2, "return-call-in-try-catch", []))).
BBQ aborts during compilation of the wasm function that does
return_call inside try-catch.
