Martin Vogel 679871aedb fix(c_lsp): remove the whole-function ASan suppression; assert the resolution it hid ...

c_lsp_process_file carried __attribute__((no_sanitize("address"))) over the
entire C LSP orchestration, excluding every direct memory access in it from
ASan -- placed for a stack-pointer-to-registry lifetime bug whose witness test
also had its assertion discarded ((void)find_resolved), so nothing could ever
prove the bug gone. Flagged by the memory-diagnostics standards report
(private/C_MEMORY_DIAGNOSTICS_STANDARDS_REPORT.md, priority 2) as the single
highest-value ASan coverage gap in the repository.

This branch's C LSP registry rework resolved the underlying lifetime: with the
suppression removed, the full c_lsp suite passes under ASan+UBSan (760 tests),
including the formerly-failing template field type resolution, whose test now
asserts the resolved call instead of discarding it.

Honest limit: the original bug predates the branch and its fix is the branch's
broad registry rework, not an isolatable commit -- so the revert-proof is
main-vs-branch (main: suppression + discarded assertion; branch: neither),
not a single-change revert-check.
