Fixed tp implementation for resistive mikromedia boards

This PR is connected to #SWMIKSDK-1697

Changes:

• middleware/tsc2003/lib/src/tsc2003.c
  • removed pen pressure detection as it doesn't work with TSC2003
• api/tp/lib/src/tp/tp.c
  • added option to clear all the touches for TSC2003 specifically

Fixes:

• now touch is detected and cleared while using TSC2003 display with LVGL project
  NOTE: STMPE approach for clearing touch inside the library itself doesn't work as it differs because it uses SPI - it sends the GPIO touch detection signal and then clears it even if we didn't release the pen whereas TSC is always sending GPIO touch detection signal until we stop touching the screen, so clearing of the touch should be done in tp.c.
