sql: remove implicit cast from MakeRecord opcode

This patch removes implicit casting from MakeRecord opcode.

Closes #4230

@TarantoolBot document
Title: remove implicit cast for comparison

After this patch-set, there will be no implicit casts for comparison.
This means that the values ​of the field types STRING, BOOLEAN and
VARBINARY can be compared with the values of the same field type.
Any numerical value can be compared with any other numerical value.

Example:

```
tarantool> box.execute([[SELECT '1' > 0;]])
---
- null
- 'Type mismatch: can not convert 1 to numeric'
...

tarantool> box.execute([[SELECT true > X'33';]])
---
- null
- 'Type mismatch: can not convert boolean to varbinary'
...

tarantool> box.execute([[SELECT 1.23 > 123;]])
---
- metadata:
  - name: 1.23 > 123
    type: boolean
  rows:
  - [false]
...
```
