[PATCH BlueZ 1/3] emulator: Remove unused le_ext_adv_type

[Kevin Dewald <kevin@simpleble.org>]

Nothing has read le_ext_adv_type since advertising sets got their own
struct le_ext_adv in commit 5145b1ea2e95 ("emulator/btdev: Add support
multiple instance of extended advertising"). Remove it along with
ext_legacy_adv_type, rather than fix that function's mapping of low
duty cycle directed advertising (0x04) to ADV_SCAN_IND.
