While the majority of the sites assumed 8-wide tabs, at least engines/e_capi.c
assumed 4-wide; in any case it is better to just follow the code style guide
and eliminate them altogether. Some addition changes (namely, curly
brackets in apps/crl.c and apps/req.c, and additional whitespace changes
in apps/s_client.c and test/provider_pkey_test.c) are made to placate
check-format-commit.sh.

Running LSX instructions requires both the hardware support and the
kernel support. The `cpucfg` instruction only tests the hardware
support, causing a SIGILL if the hardware supports LSX but the kernel
does not.
Use `getauxval(AT_HWCAP)` as the ["Software Development and Build
Convention for LoongArch Architectures"][1] manual suggests.
The LOONGARCH_HWCAP_LSX and LOONGARCH_HWCAP_LASX bits are copied from
the manual too. In Glibc 2.38 they'll be provided by <sys/auxv.h> as
well, but they are unavailable in earlier Glibc versions so we cannot
rely on it.
The getauxval syscall and Glibc wrapper are available since day one
(Linux-5.19 and Glibc-2.36) for LoongArch.
Fixes#21508.

Loongarch64 architecture defines 128 bit vector extension lsx and 256 bit
vector extension lasx. The cpucfg instruction can be used to obtain whether
the CPU has a corresponding extension. This part of code is added to prepare
for the subsequent addition of corresponding vector instruction optimization.
