feat(cm): enhance the cpu_context memory report

Currently, as part of the context_memory report, we explicitly
list the EL3, EL1 and EL2 registers and memory usage per CPU
for each world. The remaining bits in the cpu_context_t structure
are grouped and listed as other section.

This patch enhances this part, by individually listing all the
remaining bits (GPREGS, PAUTH_REGS) separately providing
a much detailed overview of the context memory consumption
amongst the registers.

The patch has been tested on the CI with the following patch
and the results are summarised precisely.
