debuginfo: Stabilize `-Z debug-macros`, `-Z collapse-macro-debuginfo` and `#[collapse_debuginfo]`

`-Z debug-macros` is "stabilized" by enabling it by default and removing.

`-Z collapse-macro-debuginfo` is stabilized as `-C collapse-macro-debuginfo`.
It now supports all typical boolean values (`parse_opt_bool`) in addition to just yes/no.

Default value of `collapse_debuginfo` was changed from `false` to `external` (i.e. collapsed if external, not collapsed if local) - https://github.com/rust-lang/rust/issues/100758#issuecomment-1935815625 describes some debugging scenarios that motivate this default as reasonable.
`#[collapse_debuginfo]` attribute without a value is no longer supported to avoid guessing the default.

Stabilization report: https://github.com/rust-lang/rust/pull/120845#issuecomment-1939145242
