The lzma module constants (FORMAT_, CHECK_, PRESET_, FILTER_, MODE_*
and MF_*) were referenced with the :const: role throughout the module
documentation but were never defined as reference targets, producing
"reference target not found" warnings under nitpicky mode.

Document these public constants with .. data:: directives, following the
convention used by the signal, socket and ssl modules, so the existing
references resolve. The now-redundant inline descriptions of the format
and check constants are condensed into linked references.
(cherry picked from commit 1530b38)

The docs build fails here because this backport removes Doc/library/lzma.rst from Doc/tools/.nitignore, but six BCJ filter references in that file are still unresolved on this branch: FILTER_X86, FILTER_IA64, FILTER_ARM, FILTER_ARMTHUMB, FILTER_POWERPC and FILTER_SPARC.

On main those names carry a leading !, which tells Sphinx to render them as plain text and skip the reference lookup. That prefix came from GH-115989 (the ARM64 and RISCV filters), which was never backported, so this branch still has the plain references.

Adding the same ! prefix to those six lines clears the warnings. I don't have push access to this branch, so a core dev would need to apply it:

 * Branch-Call-Jump (BCJ) filters:

-  * :const:`FILTER_X86`
-  * :const:`FILTER_IA64`
-  * :const:`FILTER_ARM`
-  * :const:`FILTER_ARMTHUMB`
-  * :const:`FILTER_POWERPC`
-  * :const:`FILTER_SPARC`
+  * :const:`!FILTER_X86`
+  * :const:`!FILTER_IA64`
+  * :const:`!FILTER_ARM`
+  * :const:`!FILTER_ARMTHUMB`
+  * :const:`!FILTER_POWERPC`
+  * :const:`!FILTER_SPARC`

I checked with a nitpicky docs build that this clears all the lzma.rst warnings.
