Implement write method in PostgreSQLBoolBinaryProtocolValue

[RaigorJiang]

For #35830.

Test method:

1. Create a table with a bool column in PostgreSQL

CREATE TABLE IF NOT EXISTS member_summary (
    mid VARCHAR(9) PRIMARY KEY,
    nickname VARCHAR(63),
    previous_champions_season_id BIGINT NOT NULL,
    previous_champions_tier_id  BIGINT NOT NULL,
    account_level BIGINT NOT NULL,
    profile_id BIGINT NOT NULL,
    hide_champions_raid_tier_border boolean NOT NULL,
    title_id BIGINT NOT NULL,
    block_party_invite boolean NOT NULL
);

2. Insert some records
3. Use the Go client to query the bool column through Proxy

SELECT mid, hide_champions_raid_tier_border, title_id, block_party_invite from member_summary where mid = $1

FAQ

• Why not use the Boolean.parseBoolean() method?
  Because Boolean.parseBoolean() only matches the case where the string is "true", and the default bool output by PostgreSQL is a single character "t" or "f";

If the output format is specified using ::TEXT or ::INT, the type does not meet the Binary type and will not be processed by PostgreSQLBoolBinaryProtocolValue.

Therefore, PostgreSQLBoolBinaryProtocolValue only needs to process the cases of "t" or "f".
