build: Bump auto-build libdeflate to 1.23 to avoid AVX512 not available errors (#4679)

When using `OpenImageIO_BUILD_LOCAL_DEPS` environment variable to build
all OIIO's dependency locally, OIIO's build script specifies a set of
default versions of the dependent libraries. In particular,
`ebiggers/libdeflate` is set to `1.20`.

This 1.20 version of libdeflate fails to build on platforms where AVX512
is not available and the make tool chain did not correctly tell the C
compiler about it.

```
-- Building package TIFF  locally
--         Building package libdeflate  locally
--                 Building local libdeflate 1.20 from https://github.com/ebiggers/libdeflate
/usr/tmp/ccCelbo5.s: Assembler messages:
/usr/tmp/ccCelbo5.s:649: Error: unsupported instruction `vpdpbusd'
/usr/tmp/ccCelbo5.s:650: Error: unsupported instruction `vpdpbusd'
```

This issue is fixed in libdeflate Merge Request 389
ebiggers/libdeflate#389, by explicitly calling
CMake facilities to detect whether AVX512 is present, and set compiler
preprocessor flags accordingly in the cmake file. This libdeflate MR is
after version 1.20.

To fix OIIO's build error when building this dependency locally, one can
either set `libdeflate_BUILD_VERSION` to include this patch, (for
example `export libdeflate_BUILD_VERSION=1.23`) or change the default
version in OIIO's local dependency build script to 1.23. This PR makes
the change in OIIO's local dependency build script.

Assembler build error resolved after using libdeflate v1.23 for local
TIFF build.
