i386: Fix wrong codegen for V8HF move without TARGET_AVX512F

Since _Float16 type is enabled under sse2 target, returning
V8HFmode vector without AVX512F target would generate wrong
vmovdqa64 instruction. Adjust ix86_get_ssemov to avoid this.

gcc/ChangeLog:
PR target/102812
* config/i386/i386.c (ix86_get_ssemov): Adjust HFmode vector
move to use the same logic as HImode.

gcc/testsuite/ChangeLog:
PR target/102812
* gcc.target/i386/pr102812.c: New test.
