Combine 3 different pointer returns into one structure return.

Include a cflags field in TCGTBCPUState, not filled in by

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.

target/loongarch: Add CRC feature flag and use it to gate CRC instructions

This patch replaces the obsolete IOCSR_BRD bit with CRC in cpucfg1[25],
in both LA464 and LA132 CPU initialization functions. The corresponding
field macro in `cpu.h` is updated to reflect this change.

Additionally, the availability macro `avail_CRC()` is introduced in
`translate.h` to check the CRC feature flag.

All CRC-related instruction translations are updated to be gated by
the new CRC feature flag instead of hardcoded CPU features.

This ensures correctness and configurability when enabling CRC
instructions based on hardware capabilities.
