[ 💻 Clarity VM ] Support boot contracts

[obycode]

To support the boot contracts (see Clarity contracts in here), we need support for the following Clarity functions:

• *
• +
• -
• /
• <
• <=
• >
• >=
• and
• append
• as-contract
• as-max-len?
• asserts!
• begin
• buff-to-uint-be
• concat
• default-to
• define-constant
• define-data-var
• define-fungible-token
• define-map
• define-non-fungible-token
• define-private
• define-public
• define-read-only
• element-at
• err
• filter
• fold
• ft-mint?
• ft-transfer?
• get
• get-block-info?
• hash160
• if
• is-eq
• is-none
• is-some
• len
• let
• list
• log2
• map-delete
• map-get?
• map-insert
• map-set
• match
• merge
• nft-get-owner?
• nft-mint?
• nft-transfer?
• not
• ok
• or
• pow
• print
• replace-at?
• slice?
• some
• stx-account
• stx-burn?
• stx-get-balance
• stx-transfer?
• try!
• tuple
• unwrap!
• unwrap-panic
• var-get
• var-set
• xor

I'm going to go through these and organize them into sensible groups that we can then divide up amongst us.

Ok, I've created separate issues for each of these, all labeled with "boot contracts". @Acaccia, @krl, please self-assign any of those that you'd like to take on next.

• Conditional control flow functions #62
• Sequence functions #63
• Host interface functions #64
• Buffer functions #65
• Define functions #66
• Optional/Response functions #67
• Tuple functions #68
• Computation functions #69
• Remaining simple functions for boot contracts #70
• let function #71

Done!
