[PATCH v7 039/104] tests/tcg/arm/fcvt.c: use raw opcode for FPRCVT

fcvtzs d0,s31 requires fprcvt support in compiler, which is only
available from gcc-16. Since our debian-all-test-cross container has
gcc-aarch64-14, this test will never run in CI.

Replace the concerned instruction with raw opcode, obtained from:
$ echo "fcvtzs d0, s31" | llvm-mc-22 -triple=aarch64 -mattr=fprcvt --show-encoding
fcvtzs  d0, s31 // encoding: [0xe0,0x03,0x36,0x9e]
