Implemented tuh_hid_send_report

[Tails86]

Describe the PR
Defined tuh_hid_send_report using ep_out defined in hidh_interface_t structure.

Additional context
I assume tuh_hid_send_report was originally not defined because hidh_open originally only parsed for ep_in. I don't see any reason why it shouldn't be defined now, so I took a stab at it. I tested it on an RP2040 by sending vibration to a Dualshock 4 HID controller on its OUT endpoint, 3.

Sample output:

HID Send Report 5
  0000:  05 01 00 00 FF FF 00 00 00 00 00 00 00 00 00 00  |................|
  0010:  00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00  |................|
  Queue EP 03 with 32 bytes ... hcd_edpt_xfer dev_addr 1, ep_addr 0x3, len 32
  Prepare BufCtrl: [0] = 0x54304  [1] = 0x0000
OK

Completed transfer of 32 bytes on ep 3 out

Sorry for the churn on this. I thought it would be useful to include use of tuh_hid_send_report() in example code. In the example, pressing the left and right triggers should control the left and right motors respectively. I don't plan on pushing anything further.

not a problem at all, it is much better to demonstrate API usage with example. Sorry for being late on the review, I will try to review this as soon as I could. Just approve to get ci running (required by github for 1st time contributor)

Can someone please check this? The test seemed to fail due to an issue with the test harness

[hathach]

ci failed due to hw changes to self-hosted ci runner, don't worry about it for now. I will review this soon, look like we could have an merge easy. Thank you

[hathach]

perfect ! Thank you for your PR and patient, there is nothing I could add. I only did a rebase to fix ci and will merge shortly after ci passed.
