If we don't remove all executable files in current working
directory, we might measure code size between different architecture
and configuration. This generates a wrong code size comparison
report. This commit guarantees it runs `make clean` before build
libraries for code size comparison.

This patch introduces a rounding-error-resiliant method to
calculate bits_to_limbs, and is updating `SECP224R1` and
`SECP224K1` to use it.

Use a switch instead of an array. The array was very hollow for some enum
types such as mbedtls_ssl_protocol_version (which formerly used small
values, but switched to using the protocol encoding as enum values in Mbed
TLS 3.2.0). Optimizing compilers know how to compile a switch into a lookup
table when the range warrants it.

This patch updates `ecp_mod_p_generic_raw` and corresponding
curve test methods, that depend on the NIST optimisation
parameter to not run when it is not included.
The following curves are affected:
* SECP192R1
* SECP224R1
* SECP256R1
* SECP384R1
* SECP521R1

The code size measurement script generates code size
record / comparison csv file in a more readable format.
The script won't generate new record file if there is an existing
one. It reads the record and stores data into dictionary of code_size
for comparison.

CodeSizeBase class aims to store size information for a specific
revision. It also has support to write csv report, comparison result
in a more readable format. This commit lays out foundation to
simplify code for CodeSizeComparison.

If system architecture doesn't match architecture of input argument
for default configuration, it's reported as an error.
Additionally, it prints out help message to show which architecture
and configuration option should be used.

This patch introduces the `EcpP255Raw` test class for testing
the curve using the preestablished `ecp_mod_p_generic_raw()`
test. The test's logic has been updated accordingly.
