Enable hardware watchpoints on attach for aarch64
This commit fixes a bug whereby hardware watchpoints are not used on
aarch64 when attaching to a target. The fix adds an aarch64 specialization
of post_attach which records the number of available hardware debug registers
using aarch64_linux_get_debug_reg_capacity. This implementation mirrors that
of aarch64_linux_child_post_startup_inferior which successfully enables the
use of hardware watchpoints when launching the target under the debugger.
gdb/ChangeLog:
* aarch64-linux-nat.c (post_attach): New.
(aarch64_linux_nat_target::post_attach): Override post_attach to
record the number of hardware debug registers.
gdb/testsuite/ChangeLog:
* gdb.base/watchpoint-hw-attach.c: New test.
* gdb.base/watchpoint-hw-attach.exp: New file.
