ector_software_rasterizer: Add default value for stroke's miter_limit
Summary:
Currently the default value of miter_limit is defined as 0.
miter_limit should be specified to a value other than 0. becuase it is affected by width.
See below for an explanation of this.
https://www.freetype.org/freetype2/docs/reference/ft2-glyph_stroker.html#ft_stroker_linejoin
There is no particular reason why the default value is 0x4.
It only refers to the standard of web svg.

Test Plan:
setenv("ECTOR_BACKEND", "default", 1);
elm_init(argc, argv);
Evas_Object *win = elm_win_util_standard_add(NULL, "test");
evas_object_smart_callback_add(win, "delete,request", win_del, 0);
elm_win_autodel_set(win, 1);
Evas_Object *bg = elm_bg_add(win);
elm_bg_color_set(bg, 255,255,255);
evas_object_size_hint_align_set(bg, EVAS_HINT_FILL, EVAS_HINT_FILL);
evas_object_size_hint_weight_set(bg, EVAS_HINT_EXPAND, EVAS_HINT_EXPAND);
evas_object_show(bg);
Evas *evas = evas_object_evas_get(win);
Evas_Object *vg = evas_object_vg_add(evas);
evas_object_show(vg);
Evas_Object *container = evas_vg_container_add(vg);
Evas_Object *shape = evas_vg_shape_add(container); //Default is EFL_GFX_JOIN_MITER
evas_vg_shape_append_rect(shape, 0, 0, 100 , 100, 0, 0);
evas_vg_shape_stroke_color_set(shape, 255, 0, 0, 255);
evas_vg_shape_stroke_width_set(shape, 10);
evas_vg_node_origin_set(shape, 50, 150);
shape = evas_vg_shape_add(container);
evas_vg_shape_append_rect(shape, 0, 0, 100 , 100, 0, 0);
evas_vg_shape_stroke_join_set(shape, EFL_GFX_JOIN_BEVEL);
evas_vg_shape_stroke_color_set(shape, 255, 0, 0, 255);
evas_vg_shape_stroke_width_set(shape, 10);
evas_vg_node_origin_set(shape, 200, 150);
shape = evas_vg_shape_add(container);
evas_vg_shape_append_rect(shape, 0, 0, 100 , 100, 0, 0);
evas_vg_shape_stroke_join_set(shape, EFL_GFX_JOIN_ROUND);
evas_vg_shape_stroke_color_set(shape, 255, 0, 0, 255);
evas_vg_shape_stroke_width_set(shape, 10);
evas_vg_node_origin_set(shape, 350, 150);
evas_object_vg_root_node_set(vg, container);
elm_object_content_set(bg, vg);

evas_object_resize(win, WIDTH, HEIGHT);
evas_object_show(win);
elm_run();
elm_shutdown();
