This can effectively reduce the binary size for platforms
that don't need ECX feature(~100KB).

Fixes#18586
In order to not break existing applications the OpenSSL documentation
related to SHAKE has been updated.
Background:
All digests algorithms (including XOF's) use the bitlen as the default output length.
This results in a security strength of bitlen / 2.
This means that SHAKE128 will by default have an output length of 16
bytes and a security strength of 64 bits.
For SHAKE256 the default output length is 32 bytes and has a security
strength of 128 bits.
This behaviour was present in 1.1.1 and has been duplicated in the
provider SHAKE algorithms for 3.0.
The SHAKE XOF algorithms have a security strength of
min(bitlen, output xof length in bits / 2).

This adds the -xoflen option to control the output length of the XOF
algorithms, such as SHAKE128 and SHAKE256.

Our test data (test/data.txt and test/data2.txt) are text files, but
declaring them binary means that there will be no line ending
transformation done on them. This is necessary for testing on
non-Unix platforms, where certain tests could otherwise give results
that don't match expected results.

We run two HMAC operations on the same file and confirm that both provide
us with the expected values.
