build: bumped version to v0.21.5

fixup: fixup: benchdnn: eltwise: improve input data coverage

* 1) With fp16 argument, exp() is dispatched to fp16 version as well,
* overflows and produces inf instead of an fp32 value, resulting in
* 0 in the final answer, while it should be a non-zero value exceeding trh.
* 2) MSVC math functions are invariant to compiler options leaving the
* answer same no matter what. Current threshold is low for it. Slightly
* increasing it...

src: cpu: rnn: remove macro in omp simd loop

This is to workaround a compiler bug (affects icc19.1).

cpu: gemm: make sure to return out of memory if so

Some cases were still not returning proper status in case of out of
memory.

benchdnn: ip: add DLRM training sizes

build: bumped version to v1.2.2

scratchpad: work around corrupted unique_ptr usage

src: cpu: rnn: remove unused variables in jit_uni_gru_cell_postgemm_1

It caused "label is not found" error in Xbyak after enabling AutoGrow
mode by default in jit_generator

sycl: add workaround for DPCPP compiler

get_devices() mistakenly ignores the passed device type and returns
extra devices.
