## Summary
- Fixed MySQL VARCHAR/CHAR/TEXT columns with binary collations (like
`utf8mb4_bin`) being incorrectly returned as `Buffer` instead of
`string`
- The fix checks for `character_set == 63` (binary collation) in
addition to the BINARY flag to properly distinguish true binary types
Fixes#26063
## Root Cause
PR #26011 introduced a fix for binary column handling that checked
`column.flags.BINARY` to determine if data should be returned as
`Buffer`. However, MySQL sets the BINARY flag on VARCHAR/CHAR/TEXT
columns with binary collations (like `utf8mb4_bin`) even though they
should return strings.
The proper way to detect true binary types (BINARY, VARBINARY, BLOB) is
to check if `character_set == 63` (the "binary" collation), not just the
BINARY flag.
## Changes
1. **Text Protocol** (`ResultSet.zig:143-148`): Updated binary check to
`column.flags.BINARY and column.character_set == 63`
2. **Binary Protocol** (`DecodeBinaryValue.zig:154-156`): Added
`character_set` parameter and updated binary check
## Test plan
- [ ] Added regression test `test/regression/issue/26063.test.ts` that
tests VARCHAR, CHAR, and TEXT columns with `utf8mb4_bin` collation
return strings
- [ ] Test verifies that true BINARY/VARBINARY/BLOB columns still return
Buffers

## What does this PR do?
Currently binary columns are returned as strings which means they get
corrupted when encoded in UTF8. This PR returns binary columns as
Buffers which is what user's actually expect and is also consistent with
PostgreSQL and SQLite.
### How did you verify your code works?
I added tests to verify the correct behavior. Before there were no tests
for binary columns at all.
This fixes#23991
### What does this PR do?

### What does this PR do?
Fix handling BIT(1) and BIT(N) on binary protocol and text protocol, now
behavior is consistent

### What does this PR do?
Change tinyint/bool type from mysql to number instead of bool to match
mariadb and mysql2 behavior since tinyint/bool can be bigger than 1 in
mysql
