This turns the `-Dgcrypt` build time option into a more generic
`-Dcrypto` option, which enables user to choose which cryptographic
library to link with. It currently supports libgcrypt (`libgcrypt`)
and GnuTLS (`gnutls`); for the latter, GnuTLS 3.8.2 is the minimum
required version.

This moves low-level cryptographic functions into egg/egg-keyring1.c,
to make it easy to support multiple crypto backend libraries.

These changes define the TPM2 API and add its implementations
to the incubation area (egg/).
Summary of the public API:
`egg_tpm2_initialize`: Start a TPM context.
`egg_tpm2_finalize`: End a TPM context.
`egg_tpm2_generate_master_password`: Generate and returns an
encrypted master password in `GBytes` format. TSS Marshaling,
GVariant serialization is used.
`egg_tpm2_decrypt_master_password`: Decrypts a master password
generated from `egg_tpm2_generate_master_password`. TSS
Unmarshaling, GVariant deserialization is used.
TPM2 API: TSS Enhanced System API (ESAPI)
Proposal: [extend file backend to use TPM2 derived encryption keys](https://gitlab.gnome.org/Teams/Engagement/gsoc-2021/-/issues/13)

Now with meson build system libsecret FTBFS without valgrind installed.
Two issues: (1) egg-testing.c depends on valgrind/valgrind.h unnecessarily;
(2) we forgot to add "build" directory as a header directory for meson.
This commit resolves both of them.
