feat(cmock): Enable linux target build for HID, CDC-ACM and UVC hosts

peter-marcisovsky commented 2 months ago

Description

As a part of Linux host testing, we have created a mock of USB component in the esp-idf, which will be used for testing of Class drivers within this (esp-usb) repository using Cmock test cases.

This MR adds Linux target build for:

HID Host
UVC Host

Already buildable Class drivers for linux:

CDC ACM Host

Not buildable Class drivers for linux:

MSC Host - vfs not buildable for linux
UAC Host - Ringbuffer support missing in Freerots Cmock
esp_tinyusb - vfs not buildable for linux

As discussed, rather than adding new supported target into the idf_component.yml file, (linux in this case, and other targets in future) the target list was removed from (those class drivers buildable for linux) and a target compatibility will be handled during build.

Changes

HID Host linux build + simple cmock unit test
UVC Host linux build + simple cmock unit test
CDC ACM simple cmock unit test

Testing

For each class driver buildable on Linux a simple cmock host test has been added

MR on hold, until idf core team finds a workaround for linux build without using pthread

Waiting for esp-idf GL sync wit GH, to enable linux build with the current critical section API.
