robobun d85d40ea29 fix(ffi): respect C_INCLUDE_PATH and LIBRARY_PATH env vars (#26250)
## Summary
- Make `bun:ffi`'s TinyCC compiler check standard C compiler environment
variables
- Add support for `C_INCLUDE_PATH` (include paths) and `LIBRARY_PATH`
(library paths)
- Fixes compilation on NixOS and other systems that don't use standard
FHS paths

## Test plan
- [x] Added regression test `test/regression/issue/26249.test.ts` that
verifies:
  - Single path in `C_INCLUDE_PATH` works
  - Multiple colon-separated paths in `C_INCLUDE_PATH` work
- [x] Verified test fails with system bun (without fix)
- [x] Verified test passes with debug build (with fix)
- [x] Verified existing `cc.test.ts` tests still pass

Closes #26249
