* fix(anim): relayout lv_anim_t to save 4 bytes
and fix the minor comment issue
* fix(anim): unify the type of time and animation to int32_t or uint32_t
since lv_anim_t use these types internally
* fix(anim): Don't need initialize last_task_run
since lv_anim_start will do this if the list is empty
and remove -1 to improve the accuracy
* fix(anim): remove the return value from anim_ready_handler
since no caller really use the return value
* fix(math): _lv_map check x >= max_in first
_lv_map return max_out when min_in equals max_in,
since the animation module require this behaviour
* fix(anim): normalize the time elapse by lv_map
* fix(anim): avoid iterate the list twice in anim_task
* fix(theme): the minor typo error
* fix(style): make lv_style_reset work with zerod memory
* fix(theme): fix the memory leak when lv_theme_xxx_init is called twice
due to inited variable forget to set to 1
* fix(theme): empty theme should call lv_obj_refresh_style too
and remove lv_obj_clean_style_list since the same thing is
already done in the common code(clear_styles)
* fix(lv_conf_internal.h): remove esp specific inclusion
since the same thing is already included in lv_conf_kconfig.h
* fix(library.json): change space to tab
* fix(anim): relayout lv_anim_t to save 4 bytes

* Add component.mk file for esp-idf make commands
* component.mk: Check for IDF_VER
Checks for IDF_VER when adding COMPONENT_SRCDIRS and COMPONENT_ADD_INCLUDEDIRS
to avoid definig them when not using LVGL as ESP-IDF component.
* component.mk: Remove info messages
