catch2: upgrade 3.15.0 -> 3.15.3

Three bugfix releases on the 3.15 line, per upstream release notes. 3.15.1
fixes a potential out-of-bounds access when locating the start of a broken
UTF-8 sequence during linebreaking (#3096) and TEMPLATE_LIST_TEST_CASE_METHOD
/ CATCH_TEMPLATE_PRODUCT_TEST_CASE potentially causing ODR violations (#3161).
3.15.2 stops --warn InfiniteGenerators from firing when the generator was
limited to a specific element by path filtering and silences
-Wunused-parameter in -fno-exceptions builds. 3.15.3 makes the JSON
reporter's number handling locale-independent (#3176), improves inf/NaN
handling in JSON output, and rewrites catch_discover_tests for a 4-5x speedup
with deterministic registration order. No API or ABI change; only the git tag
and SRCREV needed updating.
