stress-io-uring: reduce memory impact for smaller memory systems

Reduce iovec read/write number of blocks from 1024 to 4 at a time
to reduce mmap usage. Also open/close files on each round for more
file I/O meta date updates and improve buffer flushing on each round.
Remove direct I/O to use buffer cache. Remove D_SYNC to use buffer
cache more efficiently.

stress-cache: check RISCV_HWPROBE_EXT_ZICBOZ support for stress_cache_bzero

RISCV_HWPROBE_EXT_ZICBOZ flag from kernel headers on RISC-V was only
added in 6.7, test build will fail with an older kernel with:
    error: ‘RISCV_HWPROBE_EXT_ZICBOZ’ undeclared

Check the flag first to fix this issue.
