cryptfs: Optionally get crypto type as a property
Instead of hardcoding to "aes-cbc-essiv:sha256" with a 16 byte
key, we introduce a new property, "ro.crypto.fde_algorithm",
to allow the use of different crypto types. The only other
method we currently support is "speck128-xts-plain64" with
a 32 byte key, although new crypto types are easily added.
We intentionally derive things like the crypto name and the
keysize from the given property name. This means the code
must be changed for each new crypto type we want to support,
but that's worth it to remove the exploit vector of crypto
types with incorrect key sizes.
Due to previous refactoring CLs, this has minimal impact on
the current code other than changing what we return for
cryptfs_get_{keysize,crypto_name}.

Our code has places where we were reading in the crypt_mnt_ftr

cryptfs: Don't use bare integers for key size

cryptfs: Clarify sizing of intermediate key
Some parts of the code were intermingling constants for the master
key and the intermediate key. That works at the moment because
these are the same size. But we'll be introducing logic allowing
different sized master keys, while keeping the intermediate the
same. To aid that introduction, we use separate constants for
the intermediate key.

cryptfs: Optionally get crypt type from properties
Instead of hardcoding to "aes-cbc-essiv:sha256", we introduce a
new property, "ro.crypto.crypt_type_name", to allow the use of
different crypt methods. The only other method we currently
support is "speck128-xts-plain64", although new methods are
easily added.
We intentionally derive things like the keysize from the given
crypt name, to reduce exploit vectors. We also only accept
crypt names the code has whitelisted.
The biggest impact is replacing the hard-coded KEY_LEN_BYTES.
For compile-time buffers, we use the MAX_KEY_LEN to assure they
will be big enough for any crypt type. For run-time sizing,
we use the value derived from our property.
Bug:
73079191
Test: On an encrypted gobo, booted successfully with (1) no property set, (2) proproperty set to invalid value (and confirmed we defaulted to aes), and (3) after wiping userdata, with property set to "speck128-xts-plain64", confirmed we were using SPECK.

cryptfs: Make decrypted key buffers large enough
Looking at the EVP_DecryptUpdate() documentation, we need a
buffer which isn't just the keysize, but also provides the
cipher block length minus one byte extra. For EVP_aes_128_cbc(),
that block length is 16, but we use the maximum block length to
be safe for any future cipher change.
For two of our decrypted_master_key usages, the buffer was
already sufficiently sized. But for one of our instances,
in cryptfs_enable_internal(), the buffer was previously
smaller than this. So this CL represents a possible behavior
change if we were ever overrunning that buffer.
