[pushed] Darwin, BTF: Provide a suitable section name for BTF [PR101283].

[Iain Sandoe <iain@sandoe.co.uk>]

Hi,

In a similar manner to r12-1960-gcc8453012f75d, this provides a
placeholder section name for BTF data.  This change groups BTF
and CTF debug formats in the same segment, but keeps them in
separate sections.

As per the CTF section designation, this should be agreed or
amended to an agreed form before GCC 12 ships.

tested on x86_64-darwin17 and 18 (m32 and m64)
pushed to master, thanks
Iain
