Adds two CMake functions:

* add_module(library subdirectory): Declares an OBJECT "library" (a CMake abstraction for a collection of object files) with sources from the given subdirectory of the given library, representing a module. Isolates the module's headers by creating a subdirectory in the build directory, e.g. .build/tmp123, that contains just a symlink, e.g. .build/tmp123/basics, to the module's header directory, e.g. include/xrpl/basics, in the source directory, and putting .build/tmp123 (but not include/xrpl) on the include path of the module sources. This prevents the module sources from including headers not explicitly linked to the module in CMake with target_link_libraries.
* target_link_modules(library scope modules...): Links the library target to each of the module targets, and removes their sources from its source list (so they are not compiled and linked twice).

Uses these functions to separate and explicitly link modules in libxrpl:

    Level 01: beast
    Level 02: basics
    Level 03: json, crypto
    Level 04: protocol
    Level 05: resource, server

* Rename ASSERT to XRPL_ASSERT
* Upgrade to Anthithesis SDK 0.4.4, and use new 0.4.4 features
  * automatic cast to bool, like assert
* Add instrumentation workflow to verify build with instrumentation enabled

Replace Issue in STIssue with Asset. STIssue with MPTIssue is only used in MPT tests.
Will be used in Vault and in transactions with STIssue fields once MPT is integrated into DEX.

For example, Expected<std::uint32_t, Json::Value>, will now build even though there is animplicit conversion from unsigned int to Json::Value.

Fix `error C2039: 'set_difference': is not a member of 'std'`

Hotfix: version 2.3.1
  Reduce the peer charges for well-behaved peers
  Update conan in the "nix" CI jobs

- spec: XRPLF/XRPL-Standards#220
- amendment: "DeepFreeze"
- implemented deep freeze spec to allow token issuers to prevent currency holders from being able to acquire more of these tokens.
- in combination with normal freeze, deep freeze effectively prevents any balance trust line balance change of a currency holder (except direct issuer <-> holder payments).
- added 2 new invariant checks to verify that deep freeze cannot be enacted without normal freeze and transfer is not frozen.
- made some fixes to existing freeze handling.

This reverts commit 06a8a61.

- Also make MPTID more consistent

- Also get the branch name.
- Use rev-parse instead of describe to get a clean hash.
- Return the git hash and branch name in server_info for admin
  connections.
- Include git hash and branch name on separate lines in --version.

Prohibits LPToken holders from sending LPToken to others if they have been frozen by one of the assets in AMM pool.

This PR updates several Conan dependencies:
* boost
* date
* libarchive
* libmysqlclient
* libpq
* lz4
* onetbb
* openssl
* sqlite3
* zlib
* zstd

Make `simulate` RPC easier to use:
* Prevent the use of `seed`, `secret`, `seed_hex`, and `passphrase` fields (to avoid confusing with the signing methods).
* Add autofilling of the `NetworkID` field.
