[SYCL][DOC] Change extension names to lower case (#5607)

I found the all-upper-case names difficult to read, especially in a directory listing where all the files are upper case. Change them all to lower case. The name of the extension and the name of the file are now lower case. The name of the feature-test macro remains upper case.

 ### 3.2 Through a programming API
         
 There is an extension that introduces a filtering device selection to SYCL described in
-[SYCL\_EXT\_ONEAPI\_FILTER\_SELECTOR](../supported/SYCL_EXT_ONEAPI_FILTER_SELECTOR.asciidoc).
+[sycl\_ext\_oneapi\_filter\_selector](../supported/sycl_ext_oneapi_filter_selector.asciidoc).
 
 Similar to how SYCL_DEVICE_FILTER applies filtering to the entire process this device selector can be used to
 programmatically select the Level-Zero backend.

 This non-normative section describes the conditions when the DPC++ implementation provides an optimization benefit* for the `discard_events` property.
 
  - The queue must be constructed with the `in_order` property.
- - A kernel submitted to the queue must not use the link:../supported/SYCL_EXT_ONEAPI_ASSERT.asciidoc[fallback assert feature].
+ - A kernel submitted to the queue must not use the link:../supported/sycl_ext_oneapi_assert.asciidoc[fallback assert feature].

  - Any queue operations using Level Zero backend temporarily work without optimization.
