Adds support for Trace Interface or Trace Ingress Port (TIP) on CVA6 TIP is Interface between a RISC-V hart and the trace encoder It generates information about the instruction retired. The implementation is compliant with the Efficient Trace for RISC-V standard Version 2.0.2(https://github.com/riscv-non-isa/riscv-trace-spec/releases/download/v2.0.2/riscv-trace-spec-asciidoc.pdf), specifically: Chapter 4.1: Instruction Trace Interface Requirements Chapter 4.2: Instruction Trace Interface The current implementation supports the following TIP signals: iretire, itype, cause, tval, priv, iaddr, and time. For Instruction Type (itype) encoding, it supports the following: Exception, Interrupt, Exception or interrupt return, Nontaken branch, Taken branch, Uninferable jump. What I have been able to test so far: Simulation: Executed C binaries and observed the waveform of TIP. --------- Co-authored-by: root <darshak.sheladiya@sysgo.com> Co-authored-by: CHAUVON Guillaume <guillaume.chauvon@thalesgroup.com> Co-authored-by: JeanRochCoulon <jean-roch.coulon@thalesgroup.com>

Continuation of #3260
Development of missing features in YPB interface
Smoke tests pass in all configurations (with both AXI and OBI as noc bus)
Hello World in FPGA is OK (both 32 and 64 bits)
Linux boot is successful in 32 bits, not yet in 64 bits
