    aarch64: Update target checks for sme2 fp8
    
    Commits gcc-16-6381-g226d5fd59dc8 and gcc-16-6380-gef533d234293 had
    insufficient target checks and this caused regressions on the linaro CI
    which uses an older binutils version.
    
    This change adds the needed checks.
    
    gcc/testsuite/Changelog:
            * gcc.target/aarch64/sme2/acle-asm/cvt_mf8_bf16_x2.c: Added target checks.
            * gcc.target/aarch64/sme2/acle-asm/cvt_mf8_f16_x2.c: Likewise.
            * gcc.target/aarch64/sme2/acle-asm/cvt_mf8_f32_x4.c: Likewise.
            * gcc.target/aarch64/sme2/acle-asm/cvtn_mf8_f32_x4.c: Likewise.
            * gcc.target/aarch64/sme2/acle-asm/scale_f16_x2.c: Likewise.
            * gcc.target/aarch64/sme2/acle-asm/scale_f16_x4.c: Likewise.
            * gcc.target/aarch64/sme2/acle-asm/scale_f32_x2.c: Likewise.
            * gcc.target/aarch64/sme2/acle-asm/scale_f32_x4.c: Likewise.
            * gcc.target/aarch64/sme2/acle-asm/scale_f64_x2.c: Likewise.
            * gcc.target/aarch64/sme2/acle-asm/scale_f64_x4.c: Likewise.
