fbe439f6c2 Implement the legacy_file_format pragma 
easy implementation, sqlite claims it is a noop now

"This pragma no longer functions. It has become a no-op. The capabilities
formerly provided by PRAGMA legacy_file_format are now available using
the SQLITE_DBCONFIG_LEGACY_FILE_FORMAT option to the sqlite3_db_config()
C-language interface."

2faaa9f719 Add fix for paser not stopping at first error encounter. 
Fix is to track the state of encountering error in the `Parser` struct and set it to true whereever/whenever
we encounter an error. And the beginning of the next() we return `Ok(None)` to signal to `FallibleIterator` that we should stop parsing.

b37317f68b avoid allocations during pragma_list 
If we keep the pragma list sorted when declaring it, we can avoid
a vector allocation when printing the pragma_list.

62efbde661 use strum package to simplify PragmaName enum management 
The pragma list will only grow. The strum crate can be used to:
* automatically convert to string from enum
* automatically convert to enum from string
* implement an iterator over all elements of the enum

016b815b59 implement pragma table_info 
Both () and = variants covered. It is important to make sure that
the transaction is a read transaction, so we cannot hide all that logic
inside update_pragma, and have to make our decision before that.

a26fc1619a Merge 'Fix select X'1'; causes limbo to go in infinite loop' from Krishna Vishal 
Closes https://github.com/tursodatabase/limbo/issues/730.
Fixed `blog_literal` function to make it return `TK_ILLEGAL` token which
in turn now causes parser to stop and return `UnrecognizedTokenError`.
Added `TK_ILLEGAL` to `TokenType` Enum.
Behavior now:
```sql
SELECT X'1';  -- Odd number of hex digits -> TK_ILLEGAL -> unrecognized token error

  × unrecognized token at (1, 12)
   ╭────
 1 │ SELECT X'1';
   ·        ▲
   ·        ╰── here
   ╰────

SELECT X'AB'; -- Valid blob -> TK_BLOB -> parses successfully
�
SELECT X'G1'; -- Invalid hex digit -> TK_ILLEGAL -> unrecognized token error

  × unrecognized token at (1, 13)
   ╭────
 1 │ SELECT X'G1';
   ·        ▲
   ·        ╰── here
