  [clang] Remove -g[no-]-* bool flags from g_Group (#162750)

There are four uses of BoolGOption, and all of them are essentially debug
info feature flags, which I believe should not the enablement or
disablement of all debug info emission. `OPT_g_group` is used to control
the debug info level here:

https://github.com/llvm/llvm-project/blob/main/clang/lib/Driver/ToolChains/Clang.cpp#L4387

This doesn't cause any test failures, and seems like the right behavior
for all four flags:
* -g[no-]flag-base
* -g[no-]inline-line-tables
* -g[no-]key-instructions
* -g[no-]structor-decl-linkage-names

None of these, even in the positive form, should enable debug info
emission.

Fixes #162747
