Teensy 4.1 core updated for C++20

Kurt Eckhardt 98f01a0d06 T3.x,T4.x LC Serial half duplex support Migrating the half duplex support I did in the Stagnant and out of date PR to enhance Uarts: https://github.com/PaulStoffregen/cores/pull/419 To try to support Half duplex mode in a similar way like we do for RS485 like support. With T3.x made use of bitband address for the TX Direction setting, so Except for the begin which calls format, no code changed, we simply stored the bitband address of the TXDIR flag into the TXDIR variable that was already used for the set direction flag. For T4.x - it is a little more work as there is no bitband support on M7 processors. For GPIO there is a Set and Clear register which we use, but for the appropriate UART register there is no such setup of registers. So I have to special case we are in that mode and do it... Also since not atomic I cli/sei... Serial Half Duplex - Fix T4Serial1 and T-LC Serial1-3 Updates: T4 T4 Serial 1 did not have proper settings for IOMUXC_LPUART6_TX_SELECT_INPUT Tested T4.1 Serial1-8 Tested T3.5 Serial1-6 T3.6 - Added support for LPUART which is Serial6 which now works. T-LC Make half duplex work on T-LC on Serials1-3 Tested on on T3.5 1-6		4 jaren geleden
