This commit only replaces the bundled source and does not include any
ZFS integration changes. Because the build depends on integration
adjustments, it will fail until the accompanying integration commit is
applied.

The bound check condition should always be met because we selected
`set_basic` as our encoding type. But that code is very far away, so
assert it is true so if it is ever false we can catch it, and add a
bounds check.

Closes#14212
Clang 13.0.0 added support for `Wunused-but-set-parameter` and
`-Wunused-but-set-variable` which correctly detects two unused
variables in zstd resulting in a build failure. This commit
annotates these instances accordingly.

In FSE_createCTable(), malloc() is intentionally defined as NULL when
compiled in the kernel so the variable is unused.
zstd/lib/compress/fse_compress.c:307:12: error: variable 'size'
set but not used [-Werror,-Wunused-but-set-variable]
Additionally, in ZSTD_seqDecompressedSize() the assert is compiled
out similarly resulting in an unused variable.

'litLengthSum' set but not used [-Werror,-Wunused-but-set-variable]

It's much nicer to import from upstream this way, and compiles
faster too.
Everything in lib/ is unmodified 1.4.5.
