Issue:
Rework or remove everything related to `VarAddress` (`addr_var`) from the standard library
In [Version 10](https://github.com/ton-blockchain/ton/blob/master/doc/GlobalVersions.md#version-10) of the TON Blockchain, support of `addr_var` addresses was almost completely cut down. For example, the `addr_var` cannot be a destination address of external messages, and if it's used for a destination address of an internal message, it is rewritten as an `addr_std`.

Furthermore, these TVM instructions drop support for anycast addresses and `addr_var`: `LDMSGADDR(Q)`, `PARSEMSGADDR(Q)`, `REWRITESTDADDR(Q)`, `REWRITEVARADDR(Q)`. They throw an exit code (usually 9) whenever one attempts to apply them to anything, including `addr_var` addresses.

That hits our `parseVarAddress()` function and the respective `VarAddress` struct. We should either remove those entirely or deprecate/turn into a no-op.

Hints from issue comments:
@i582: I think it's worth making a hard deprecate in the compiler to give a clear error (unlike if you just remove them completely) where all the root causes are described.

+### Breaking changes
+
+- Compiler now reports an error if `VarAddress` or `parseVarAddress()` is used, since starting
+  from [TVM 10](https://github.com/ton-blockchain/ton/blob/master/doc/GlobalVersions.md#version-10) they are mostly not supported: PR [#3067](https://github.com/tact-lang/tact/pull/3067).

 ### Language features
 
 - [fix] Compiler now correctly handles optional slices, builders, and strings when generating serialization logic: PR [#3053](https://github.com/tact-lang/tact/pull/3053)
