ui: Support controller peripherals and XMU devices (xemu-project#1315)

* Added XMU Settings to the Input Screen

* Added Peripherals to config

* Prevent overwriting existing XMUs

* Added blockdev.h to try to fix the MacOS build

* Fixed some issues that antangelo pointed out

* Moved the peripheralType and param vars into the loop

* Moved fatx.h and fatx.c to ui\thirdparty\fatx

* Added Validation for Peripheral Settings

* Fixed some nits that were pointed out

* don't pass NULL into xemu_settings_set_string

* Changes following Matt's recommendations

* Changes to XMU FilePicker

* XMU image auto-bind logic refactor

* renamed peripheralType to peripheral_type

* removed unnecessary calls to g_strdup_printf and g_free

* Cleaned up some comments, removed an unnecessary variable

* handle overwrite prompt in Windows

* Fixed some code format and style inconsistencies

* More formatting fixes

* Fixed a few memory leaks

* qemu_access: check for Read and Write access

* Run clang-format

* Remove unused xemu_new_xmu declaration

* Fix use after free in rebind code
