target/loongarch: Guard BCEQZ/BCNEZ instructions with FP feature
The BCEQZ and BCNEZ instructions depend on access to condition codes
from floating-point comparisons. Previously, these instructions were
unconditionally enabled for 64-bit targets.
This patch updates their translation to be gated under the `FP` feature
flag instead, ensuring they are only available when the floating-point
unit is present.
This improves correctness for CPUs lacking floating-point support.
