Add the UBSAN_LOCAL_BOUNDS check for Clang build

Explanations from the Linux kernel commit 6a6155f664e31c9be43cd:

When the kernel is compiled with Clang, -fsanitize=bounds expands to
-fsanitize=array-bounds and -fsanitize=local-bounds.

Enabling -fsanitize=local-bounds with Clang has the side-effect of
inserting traps.

That's why UBSAN_LOCAL_BOUNDS can enable the 'local-bounds' option
only when UBSAN_TRAP is enabled.

Don't add CmdlineChecks in add_kconfig_checks() to avoid wrong results
when the tool doesn't check the cmdline.

A common pattern for checking the 'param_x' cmdline parameter
that __overrides__ the 'PARAM_X_DEFAULT' kconfig option:
  l += [OR(CmdlineCheck(reason, decision, 'param_x', '1'),

CC_STACKPROTECTOR_AUTO -- the best stack-protector that compiler provides.
