[rocprofv3] signal handler fix (#332)

* rocprofv3: LD_PRELOAD for signal and sigaction

- wrappers around `signal` and `sigaction` to prevent applications which install signal handlers to replace the rocprofv3 signal handlers
- minor tweaks to buffer sizes (use page_size instead of
KiB)

* [DO NOT COMMIT] extra logging

* Switch git submodule url for perfetto

- use GitHub URL as this is more accessible

* Update ring_buffer<Tp>

- account for alignment padding

* Update buffered_output

- track number of bytes stored
- add nullptr checks

* Update tmp_file_buffer

- track number of bytes
- read_tmp_file does not create tmp file if it does not already exist

* Update tmp_file

- add exists member function for checking whether temporary file already exists
- tweak remove() implementation

* Update config.hpp

- add option to enable/disable signal handlers
- add option for minimum_output_bytes

* Make signal, sigaction functions visible

* rocprofv3 tool updates

- chained signals
- override the signal handler(s) installed by the application
- improve cleanup of temporary files
- support minimum output bytes

* Add commandline support

* fixing test

* minor fix

* minor fix

* fix clang issue

* fix

* Adding docs

* review comments

* review changes

* review

* YUV pulldown additions to rocdecode
