Fix intervalometer ramp-rate enum property registration

Browse Source 
Fixed GLib-GObject-CRITICAL errors caused by incorrect enum type
registration in the intervalometer plugin.

The issue was on line 189 where g_param_spec_enum() was being called
with GST_TYPE_INTERVALOMETER (the class type) instead of a proper
enum GType for the ramp-rate property.

Changes:
- Added gst_intervalometer_ramp_rate_get_type() function to properly
  register the GstIntervalometerRampRate enum as a GType
- Defined GST_TYPE_INTERVALOMETER_RAMP_RATE macro
- Updated PROP_RAMP_RATE property installation to use the correct
  enum type

This fixes the following errors that appeared during pipeline launch:
- g_param_spec_enum: assertion 'G_TYPE_IS_ENUM (enum_type)' failed
- validate_pspec_to_install: assertion 'G_IS_PARAM_SPEC (pspec)' failed
- g_param_spec_ref_sink: assertion 'G_IS_PARAM_SPEC (pspec)' failed
- g_param_spec_unref: assertion 'G_IS_PARAM_SPEC (pspec)' failed
