Memory leak(s) in TriCore target

[relapids]

Steps to reproduce: Build with LeakSanitizer (enabled by default with AddressSanitizer on Linux) and run the tests/samples.

Example build steps:

$ cmake -S ../repo/ -B . -G Ninja -D CMAKE_C_COMPILER=clang -D CMAKE_C_FLAGS=-fsanitize=address -D CMAKE_BUILD_TYPE=Debug
$ cmake --build .

Output for sample_tricore:

Emulate TriCore code
>>> Tracing basic block at 0x10000, block size = 0x6
>>> Tracing instruction at 0x10000, instruction size = 0x2
>>> Tracing instruction at 0x10002, instruction size = 0x4
>>> Emulation done. Below is the CPU context
>>> d0 = 0x8000

SUMMARY: AddressSanitizer: 36864 byte(s) leaked in 6 allocation(s).

It looks like the Tricore target is missing a unicorn_release function being registered in tricore_uc_init to clean up any allocations.
